Jessica Lowndes, AnnaLynne McCord, and Jessica Stroup return in "90210."

The CW will not officially reveal its schedule until Thursday morning, which is when yours truly will be on a plane. Not to worry; the blog will be updated with the official schedule soon after it is released.  Besides, enough information has trickled into the trades for us to talk about a few important details and make some educated guesses as to where new series will land on the schedule. Or, we should say, the first version of its schedule, because almost every network tweaks its lineup once the upfronts come to a close.

Before we get to the new stuff, here’s a round-up of the current news: “One Tree Hill”  was officially picked up earlier this week, joining previously announced CW renewals “90210,” “Life Unexpected,” “The Vampire Diaries,” “Gossip Girl,” “America’s Next Top Model,” “Supernatural,” and “Smallville.” Additionally, the CW confirmed today that “Smallville’s” 10th season will be its last.

Gone from the schedule (thereby proving there is a Higher Power that cares for us all) are “Melrose Place,” “High Society,” “Fly Girls” and this season’s “here today, gone tomorrow” prizewinner, “The Beautiful Life: TBL,” which barely made it out of the gate. Their departure from the TV landscape will doubtless be mourned by…someone.

On the other hand, if they hadn’t been cleared away, The CW wouldn’t have any place to put its new additions, “Nikita” and “Hellcats.”

“Nikita” is a reboot of the franchise that began with Luc Besson’s (freaking awesome) cult action film “La Femme Nikita,” which was remade for American audiences as the awful “Point of No Return” starring Bridget Fonda.  The character of Nikita resurfaced in a Canadian-produced action drama that ran for about five seasons on USA Network, and was played by Peta Wilson. Maggie Q takes over the role in the new version, which also has her going rogue.

The first TV version of “La Femme Nikita,” it must be mentioned, was part of a late-’90s, early ’00s girl power trend on television that included “Buffy the Vampire Slayer,” “Xena: Warrior Princess,”  and “Alias.” Considering that we live in a time in which Paris Hilton, the Kardashians and  “Girls Gone Wild” are celebrated pop culture fixtures, returning “Nikita” to TV is — in concept — a breath of fresh air.

On the other hand, it’s on The CW. If someone doesn’t screw it up, there’s still the question of whether it’ll pull the ratings to survive. With McG as an executive producer, there is hope.

“Nikita” is joined on the schedule by “Hellcats,” a drama about competitive cheerleading starring Aly Michalka and Ashley Tisdale. If “Nikita” is a nod to what The CW used to be (in its previous incarnations, UPN and the WB), “Hellcats” seems to fit in perfectly with what the tiny broadcast network is now.

Question is, where will they appear on the schedule? Currently there are two obvious opportunities, one on Wednesday nights, and one on Fridays, where “Smallville” has been able to hold on to its audience.   The CW’s schedulers have been known to slide veterans into different timeslots in the hope of finding a perfect pairing so really, it’s foolish to guess what the network’s lineup will look like. But why should that stop us?

Keep reading after the jump for our scheduling guesswork.

MONDAYS

The one-two punch of “Gossip Girl” and “One Tree Hill” seemed to work out just fine this season in spite of creative problems with the former’s story arc. “OTH” is a veteran whose audience has grown up and stuck with it, and the trend-setting “Gossip Girl” is now as acceptable among adults as it is with tween and teens. We doubt the network will mess with this.

TUESDAYS

Since “Life Unexpected” was a late addition to this season’s schedule, it’s highly possible that it will move to Wednesdays in order to team up “Hellcats” and “90210.”

WEDNESDAYS

On the other hand, if “Hellcats” is as bitchy as it sounds, coupling it with “America’s Next Top Model” wouldn’t be the worst idea.

Bloody lust is so sexy. Paul Wesley stars in "The Vampire Diaries."

THURSDAYS

Here’s where things get a bit dicey. “The Vampire Diaries” is this season’s clearest hit, not only among new shows but in the context of the schedule at large. It finally gave The CW a real presence on Thursday nights.  At the same time, it’s probably popular enough to take its audience with it if it were to move. The obvious destination for it would probably be Friday.

Please. Not going to happen.

“Supernatural” is another veteran series that paired beautifully with “Smallville” on Thursdays in season past. One should not be surprised if The CW decides to reunite old friends  — especially considering that the repeats of this past season’s episodes will air at 9 o’clock Fridays this summer. “Supernatural’s” audience probably won’t be too excited to see its show move to Fridays next fall, but they’re (we’re!) passionate, and most of them (us!) will follow.  That leaves 9 o’clock Thursdays open for “Nikita” to slide in,  and with potent “Vampire” as its lead-in, “Nikita” would have one of the best slots on the CW’s schedule.

FRIDAYS

On the flipside, “Smallville” fans could already be familiar with “Nikita’s” mythology, so the network could opt to create an end-of-the-week destination for action genre viewers.

Now it’s your turn.  Have any guesses as to how the deck will be shuffled?
