Let me start by saying I am not one of these anti-classic WoW people, I am looking forward to it and can't wait to see how they implement it.
That being said, I wonder what kind of interest there would be in WoW retail servers that were "vanillaized"? By "vanillaized" I mean the following were removed:
1) No merged realms
2) No cross realm
3) No LFR
4) No LFG
5) No realm hopping
6) No cross-realm BG's
Basically, you are forced to interact with people on your server. The people you see at the AH or in the middle of Winterfel, are on your server. If you get a bad reputation for cheating, scamming, or just being a dick, that reputation haunts you on your server. The same with good a good reputation. If you camp some low level dude, he can remember your name and hunt you down once he gets geared, or he can get guildiees to help haunt you down and you dont phase away to another realm just because you crossed a zone barrier. Etc. Etc.
Part of me wonders if these changes wouldnt give me 80% of what I want from Classic WoW? Maybe this sort of server with current retail content, should be an option in addition to Classic WoW?
