Doom Stone release...5/11 or 5/13

Hello Portal Masters!!!  According to a few sources at a TRU, Doom Stone, the last swapper, is being held in store til 5/11 OR 5/13, depending on the employee.  Sunday, 5/11 could be the release date, since that's the typical start of the sales week, OR it could be on 5/13, since that's the typical release date of new video games...either way, it looks like sometime next week we can all complete the swapper collection!!!
