The Vampire Dairies isn’t coming back until October. Same for Arrow and Hart of Dixie. And those new CW shows like Reign and Tomorrow People? Yeah, October. For the second year in a row, CW is preferring to avoid the late September demo-derby of premieres launched by the Big 4 networks and instead is waiting for some dust to settle before launching its lineup (the network figures the strategy worked out pretty well for Arrow last fall). CBS is once again launching nearly everything during the traditional premiere week, while NBC is taking a somewhat more staggered approach.
