because the ps3 will be like the wii but with better graphics and blu ray

I highly doubt it. Nintendos consoles are a lot cheaper than sonys consoles so even with motion control it wont affect anything. Nintendo also have the DS which more often than not sells more than twice as much as the PSP so will always make more money.

No, look at the price of the ps3 and price of the games, and also the type of game available for it. Its totally different to what the wii was going for.

The motion controller was only one of the things which made the wii a success. Also PS3 graphics look very dated compared to what is available on the PC with DX10 and DX11. I think sony will have to follow Nintendo along the affordability route for their next console.

nope, if anything, sony will lose money on their foray into motion control
nintendo already had a huge fanbase, now with the wii, its bigger than ever.
plus like everyone else mentioned they got the ds. and coming soon the dsXL
