It's been proven in Japan that games sell the console, not the price. PS3 has had 2 price drops while sales didn't increase at all!
So yeah, the 360 will see a boost and will probably outsell the PS3 because of Infinite Undiscovery. But it is a new IP and has received mediocre-okay reviews as of now, so the effect won't be as big as the effect ToV had.
Anything can happen, but I wouldn't count on it.
