SF 20th anniversary - 2007 or 08?

Dumb question:

IF SF1 came out in 1987 why is the 20th anniversary being celebrated in 08?


They’re running a little late… HD remix should be out. The announcement of SF4, i’m guessing is the anniversary gift to all who play street fighter.

True, SFIV is the anniversary gift…
But i think that HD remix should be that gift because it should be released late 07…
but hey, wut can we do?

I believe that SF1 came out in 1988 in the USA. And now Capcom USA owns the street fighter license. Meaning the anniversary is celebrated in 08.
