When this gen is over, will the PS3 outsell the 360 IN AMERICA?

If we define the end of the gen as when the first next gen system is released, then no.

The PS3 could get close to the 360 towards the end of the gen and if Sony manages to keep the PS3 on the market for a little while into the next gen, it might just eke out enough sales to pass the 360.
