If you planned on buying a PS Vita soon, might as well get one of the WiFi systems now to pick up a 4GB memory card and a copy of the new Mortal Kombat for free.
Best Buy is also running a PS Vita promotion that throws in a free game (from a selection of four – ModNation Racers, MLB 12, Unit 13, or Uncharted: Golden Abyss), as well as a three-month PlayStation Plus subscription.
