A new teaser site, projectv1.com, has popped up with a big red "V" in front of a static-y gray helmet that also contains a "V" on it, toward the top. There is a countdown timer set to end on May 30, 2014, and below that, the words "HE IS COMING..." followed by the hashtag #PROJECTV1. Due to the helmet and the site saying "He", the best guess I've seen on Twitter so far is that it's the return of Viewtiful Joe.
Whether it's Viewtiful Joe or something else entirely, the good news is that, no matter what your platform of choice is, you'll be able to play it. A look at the source code reveals that "PS4, PS3, Xbox360, XboxONE, PSvita, 3DS, PC, Wii, Wii U" are all listed. Seeing that the Vita and 3DS are listed, Viewtiful Joe is certainly a viable option, as it's a side-scrolling beat'em-up series, which would easily work on those handhelds. We'll find out for sure next Friday!
