Probably not. Many casual (as in, not dedicated to gaming) consumers will see the $400 price versus the $200 Wii, then see more games that support motion, and they'll side with the Wii. To say that NOBODY would get a PS3 for it would be folly, but I don't think the uptick will be that great, say, about a 5% increase over expected sales.
