Could Uncharted 2 push PS3 sales above 300,000 and if so, how much?

I think sales of PS3 should stay the same as this week.

In other words, the sales of the PS3 should be a little lower due to the PS3 slim + price cut effect wearing off, but the release of U2 will boost sales enough to keep selling the PS3 at its current pace.
