RE: Is Conquest Actually Out?
Yes, it's technically out. Being a Monday Nintendo release however, it's unfortunately plagued with shipment issues. It's for this reason GameStop will list the release as Tuesday instead, because they know they won't likely have their shipment of the game on the proper street date (and even if they get it, the Tuesday date prevents them from selling it). Most people are having luck with Wal-Mart, Toys R Us and Target but don't get your hopes up until tomorrow.
As a side note for those looking to pick up the game, GameStop is currently charging $34.99 which is roughly $5 over the MSRP set by Nintendo (they're notorious for this). Since the passwords they're offering are universal I'd advise purchasing it elsewhere unless it's your only option.
