http://www.metacritic.com/tv/seasons/2007fall/bydate.shtml I'm personally waiting for Chuck (NBC), Cops (FOX), Prison Break (FOX), Survivor: China (!!) on CBS, and of course Heroes (NBC)
There are some interesting new shows premiering this season:
"K-Ville" on FOX - a cop drama set in the post-Katrina new Orleans
"Carpoolers" on ABC - Four men use their daily commute as a male bonding session
Chuck on NBC - A computer geek accidentally becomes a top government agent
Big Shots om NBC - Dylan McDermott is one of four CEO friends
Online Nation on CW - 30-minute showcase for user-generated content (that should be interesting!)
There is a lot to look forward this fall, so get ready!
