I've been considering the possibility of wizards reprinting the shocklands in Innistrad, and I think there's a small chance of seeing the allied ones in the fall. Flavor wise, we have Bloodcrypt-vampires, Stomping Ground – Werewolves, Watery Grave-Zombies. Those all seem to fit, and are the confirmed tribes for those colour pairs. Temple Garden-? and Hallowed Fountain-Ghosts don't seem to fit as well in a gothic horror themed set.

Matt- Good call on the discrepancies on Shocklands, maybe not a chance to make much profit on MTGO if they've shot up that far, but if you plan to play the format, it may still be wise to get in on the ones you'll want to be playing with. I'm liking the thoughtseize move more and more as I think about it, as ripping apart hands is going to be the best way to defend against the degeneracy that will likely show its face in the formats infancy.
