While this was cool, it wasn't a surprise to anyone, either (someone I know from another website I visit called it "the gaming industry's worst-kept secret"). Still, when it was officially announced, even though we all saw it coming, most people were happy to hear it.
Personally, I was a little skeptical at first until Capcom released a fact sheet about the game. Most people were probably thrilled to hear about the netplay, or the anti-aliasing options. What finally got me excited about the release was the mention that the game would be based off of the Sega Dreamcast version.
What does this mean? Marvel Vs. Capcom 2 will be "Arcade Perfect", meaning that there are no gameplay-based phenomena that occur unless it would happen in the original arcade version. If you don't know why this is important, get ready for an important lesson."
