Curious. I'm continually refreshing my email: they ought to send it as soon as it's released... I still don't see the use of preregistration as I'm doing the same clicking of the link over and over until it works. I guess it's intended for those who don't frequent a site like TA.
Super Mario Run did the same thing and I never got my Pre Reg email until like a day later so I dont trust them to be super on the ball.
Don't count on the pre-registration email thing kicking in automatically once the game's out. You're just on Capcom's mailing list. Keep mashing that link blue rocket provided...it's legit. The game SHOULD show up either in a matter of minutes, or a few hours at worst.
I do remember another one that frustrated me like this and that was Final Fantasy opera omnia (Japan only game as of now) You could download it and all but couldn't actually play the game and that lasted for almost a solid 24 hours So I would fire up the game repeatedly to see if it was live and just a menu screen it sucked This is worse tho ha
it's the actual link, doucebag, not my fault it's not available yet http://www.us.capcommobile.com/street-fighter-iv-ce
