I dont think your going to need your 360. Metal Gear Rising looks set to come out on the PS3 too.

I agree the whole wi-fi thing not being built in it a bit annoying alright. And your right, Blu Ray is doing well thanks to the PS3 [im pretty sure even as a Blu Ray player alone it sells more than any stand alone Blu Ray player] but the uptake on the market is still extremely slow compared to how DVD blew up around the time of the PS2 launch. The recession too makes Blu Ray even tougher to sell.
The wii being better than the 360 though? Nah, brah. Both the PS3 and the 360 have an insane amount of 'real' games compared to the wii.
