Preordering NBA 2K11 from GameStop will land your Xbox Live or PlayStation Home avatar a Michael Jordan No. 23 Bulls jersey for free. I hear if you pre-order Rock Band: Lollapalooza you get a Gary Trent Miami Heat model instead.
Home gets the white Home jersey (get it? Get it?) Xbox Live gets the red road one (below). They come courtesy of a code that you pick up or have emailed to you when you pay for the game.
NBA 2K11 is due out October 5.
