What's even more astounding is all of this information is just out there, floating around the Internet. We didn't have to collect masks or unlock a blood-filled casket or find key cards or anything. For now, we're cautiously taking everything we read with a grain of salt, even if it is the Xbox Marketplace. We've also reached out to Capcom for confirmation of these features.
Update: We have received a missive from Capcom: "We'll have further clarification in the coming weeks." Tantalizing!
