I think the PS4 should wind up at ~6-8M. It all depends on when, and by how much, Sony decides to cut the PS4 price. If it's in the next couple of months and a full $100, it'll be closer to 8. If it's only by $50 and later in the year, it'll be closer to 6. And I'm Sony a game or two for late this year/early next year, to help give it a boost during the holidays, as well.
