The English version of the official Tatsunoko vs. Capcom website has hit the web, you can find it here http://tatsunoko.vscapcom.com/index.html.

The site features a basic overview of the game, along with some artwork, a movie and general information about a handful of characters.

While there's not a lot here yet, it looks like Capcom has set up this site to grow considerably as the game gets closer to launch.
