Capcom recently responded to a fan question over at Capcom-Unity on whether there would be any ports of PS3/360 games coming to Wii U.
"With regard to WiiU, in general we're looking forward, not back so late ports are generally not on the table," Capcom's Christian Svensson responded.
This suggests we won't be seeing Resident Evil 6 on Nintendo's console, but perhaps Capcom have bigger plans...
