According to Gamestop, June 22, 2010 (the 21st is the day it'll ship to stores) is the day millions of fence-sitting North Americans will have to make a decision on which console they're going to buy Final Fantasy XIII for. This is in spite of advertisements during E3 09 which hyped the game for a Spring 2010 release, and word from Yoichi Wada that the release date would be revealed during Tokyo Game Show.
What lends this date even more weight is the fact that it wasn't given the company's usual generic place holder "first day of the month" release date like Max Payne 3 or Fallout New Vegas. The date also happens to fall mere days after the conclusion to E3 2010, and is currently one of the more quiet gaming months of the coming year. I'm hoping this date ends up being the real deal, or at least within a week or so of the actual date. It would sure make my summer really awesome.
