In an interview with French gamesite Jeux-France creator of ResidentEvil

S Minoru Nakai talks Revolution.
He made many referalls to if Capcom ported ResidentEvil5 to Revolution it wouldnt meet the Revolutions potential.
ResidentEvil 5 ported would most likely dissapoint fans and Capcom seems to realize this, RE5 wouldnt be up to standards with other FPS's due for the Revolution and would most likely crash and fall way short of Sales standards.
Capcom's Exec told Jeux-France that Capcom will create a title capitalizing on the Revolution and its potential and features before creating a ResidentEvil game. To gain experiance with the Revolution and make sure that the ResidentEvil brand which is currently viewed as infowlable doesnt end up taking any damage.
It seems ResidentEvil 5 will not make an appearance on the Nintendo Revolution but it looks very promising that ResidentEvil 6 may not be availible on X-360 or PS3. The fact is this time around if Capcom makes a ResidentEvil game based around the Revolution they will not be able to port it without dissapointing fans!
