I hope they don't go overboard with the standalone releases. I'm all for BOBW and Redemption, and probably the other season cliffhangers, but I will draw the line at stinkers like Gambit. No thank you.
These standalone releases only make sense for season finales/openers, because it gives the diehard fans an opportunity to have the season premiere months early. Releasing in-season episodes with exclusive features will only piss off the fans. It would look like CBS was withholding features from the season set to force the fan to buy it twice, much like with Day-1 DLC for a video game.
