At the very least this alleviates concerns I had about the arcade version in the US to a point. It seems that there is still no distributor for the game but Capcom was obviously interested in showing off the arcade version to people as opposed to the console version. From the report it appears as though they have designed the game to play much like SF2, but with the newer graphics and a few extra features and as they state:
Street Fighter IV may sound like it’s been a bit dumbed down for the masses, but with Focus attacks, EX moves, Super attacks and Ultra combos all thrown into the mix, there’s more than enough fighting strategy here for those who have the will to unlock it.
The roster is a little small (if you’re used to the KOF series) sporting 16 characters which includes the original 12 characters from SF2: Championship Edition and four new characters.
So now we just need Capcom to find a distributor so that importing the game won’t have to be the path most operators take.
