OK folks, we can all breathe easier now. Bull Moose has it listed for $69. Chances are Import CDs or Amazon USA will come in even lower.
EDIT: I also notice that Bull Moose's listing says that the MSRP for the set is $89.98, so you certainly won't see any U.S. retailer charging more than that.
Thanks for letting us know, privateuniverse!
I may buy from Bull Moose but I will wait for amazon.com to post their preorder page and price before deciding who to buy from, but as long as it's less than $100 and I can get it on release day, that's all that matters to me!
