Looks like our favorite Upper East Siders are moving…but not far.

The CW confirms word of a schedule changeup: One Tree Hill and Gossip Girl are switching time slots on Monday nights, with OTH launching at 8 p.m. and Gossip Girl moving to 9 p.m.

Could the move mean our graduating Gossip Girl characters are growing up and need a later hour for more adult storylines? Read on for the scoop, plus the official list of fall premiere dates for all your CW faves!

According to a network rep, it’s not the aging up of the GG characters that’s causing the move, but rather the swap is because (a) “OTH has always been a self-starter” (meaning that its success is not lead-in dependent) and (b) because 9 p.m. is a “less competitive” time period for CW crown jewel Gossip Girl.

For the record, at 9 p.m. on Mondays this fall, GG will be facing off against Two and a Half Men and The Big Bang Theory on CBS, Trauma on NBC, Dancing with the Stars on ABC and Lie to Me on Fox. The 8 p.m. competition would have been House on Fox, HIMYM and the new Jenna Elfman comedy Accidentally on Purpose on CBS, Heroes on NBC and, yep, Dancing with the Stars on ABC. (The 9 p.m. hour does sound less brutal!)

Gossip Girl Season 3 starts on Monday September 14 at 9pm/8c. You can get the full CW run down here

We’re trying to figure out whether to keep the video archive as it currently is (downloadable), or to possibly switch it to something streaming (example). Let us know which way you prefer to view the videos in the comments so we can decide what is the best option! Thank you!
