Wizards is in business to make money. Is that honestly so hard to understand? /Rant Please, please, please understand that WOTC makes more money selling Core Rulebooks, than they do by selling "Urban Growth Boundaries of the Drow", or the latest FR sourcebook. You'll see WOTC release 4e when they please. It's never been about cultivating a hobby, for any of the current publishers (Read: Not bankrupt) It's about selling books. If you think otherwise, then you're already in FANTASYLAND, you don't need to play an RPG.
