I suspect that a lot of the sales from next week will be "rebound" from this week. That is, people waited this week to buy their systems next week to get a good deal, and PS3 sales were way down this week because of it.
The Walmart $100 gift card deal will have a bigger effect than MGS4. I think we'll see about 200k sales for the PS3, perhaps challenging the Wii for a week before returning to the cellar.
[edit] Adding answers:
(1) 120K
(2) 30K (ish)
(3) That's a joke, right? The PS3 won't reach 1/2 of the Wii's sales for June in North America.
