Retail stores are not a reliable source for video game release dates.  The gamestop clerk was guessing as the myriad of game pre-order websites have (almost all showing their own "release date").  June 2nd is by know means "confirmed" because a gamestop clerk said so.  We link to the section explaining all the discussion regarding the release date because there has been no official date given.  Wikipedia is not for original research, and picking the likely date out of the options is original research.  We simply supply all the information, but thanks for your contributions, and I didn't know they were reserving copies yet, I'll be reserving mine soon ).
