Actually, why buy the import version of KOF 99 Evo when its been announced that the game will be coming to the U.S.? Personally, I prefer to wait for a domestic release of DC games if possible, I just prefer the manual and CD case to be in English.
I do make an exception when I'm not sure if the game will hit the U.S., as is the case with Last Blade 2: Final Edition (December import release) and Guilty Gear X (also December import release). Although these two titles are very likely to come out here, I'm not willing to take the chance . . . I'll pick up the imports, and if the domestic ones hit later, I'll get those too.
