various Korean websites. As you can see, the image focuses in on Mega Man X, which may indicate the X series will be involved in some way. Its legitimacy is questionable, however. The Mega Man Network notes:
Some things seem to check out, with what little I can investigate. NeoWiz and Capcom are listed, and are obviously the creators of the game. “Pmang” is NeoWiz’s online casual game portal. However, some things still bug me. The image has no logo or other write-up, the Capcom copyright date is in 2007, and no sites outside of Korea have reported on this picture (until this one I suppose).
It looks legitimate, that's for sure, but until something a bit more official pops up, I'd take this with a grain of salt.
Thanks to everyone who sent this in!
