A typo of such magnitude in the registration form would almost certainly have not passed EA's QA department before the game had shipped.
If FIFA 08 for the Mac is in the works, it will likely use Cider, TransGaming's portability engine that is currently being used in EA recent releases such as Harry Potter and the Order of the Phoenix, Need for Speed: Carbon, Command & Conquer 3, and Battlefield 2142. Two EA Sports games, Madden 08 and Tiger Woods PGA TOUR 2008 are scheduled to ship next week.
FIFA 08 recently began shipping for the PlayStation 2, PlayStation 3, PSP, Nintendo WII, XBOX 360, PC, Nintendo DS and Mobile.
