Slightly off topic: I find it laughable when people use these two reasons for why the PS3 isn't struggling or why it will eventually "win"
1) It's doing better than the PS2 did at the same point in it's life span
2) It's sold better then the 360 in Year X
I find it absolutely ridiculous that people don't understand the concept of market growth. Duh those 2 points are true, BUT the same could be said about the Wii VS any of the consoles. The point is, as more people enter the market, we're likely to see more growth in sales. The issue with the PS3 is, it's growth isn't as substantial as that of the Wii and the 360 (hence why it's still in 3rd despite those 2 points above). That's why the last generation outsold every gen before it, and despite the financial crisis, some still predict this gen's total console sales to surpass last generation.
Personally, I believe the PS3 will catch the 360 by the end of generation, I don't doubt that. The problem is, when it does, will the 360 still be the flagship home console for Microsoft?
I doubt the Wii will be surpassed by either.
