This seems like a bad idea. The way Wii uses motion controls is what sets it apart, tacking them on like this is going to suck. Wii games by third parties generally suck anyway with a few golden exceptions, and all the ports of Wii titles sucked (eg, Rayman) because of the lack of motion controls. The best case scenario is that these third party games can be ported over to the PS3 -- but who gives a shit, because since the Wii's hardware is far less powerful than the PS3 or 360, the graphics of a ported Wii game will look like garbage compared to what a PS3 owner is used to if they only play PS3 and do not own a Wii, and if they do own a Wii, why not just get the Wii version? Plus, they are neglecting the fact that the audiences for the Wii and PS3 in and of themselves are vastly different, and one of the most appealing things about the Wii is its price tag.
Seriously, though, Sony needs to stop this and get some fun games out that aren't multiplatform so I can use my PS3 for more than folding and blu-ray. If I want to play with waggle stuff, I'll play on the Wii - which doesn't even have it in every game! Its really sad that Time Crisis 4 was so lackluster, and the Wii is getting far more quality rail shooters -- I'd love to see those in glorios HD compared to 480P.
I'm waiting to get Ratchet & Clank: Future and I'm still debating what console to get GTAIV for, but it looks like the 360 may be it because of the achievements, supposedly exclusive DLC, and my fear of needing an installation for the PS3 version. I'd like to get Folklore if I can find it cheap like everyone else has, but right now my backlog is so big that I can't justify a $60 game -- if there was anything even worth buying at the moment. I wouldn't mind playing Resistance, but I've got enough shooters on the 360 (mostly crossplatform, but I got my 360 before my PS3) that I really don't need anymore. Every game is an FPS nowadays, but that's a rant for another day.
This certainly turned into a little essay that got derailed. In conclusion, having all three consoles makes me feel nonpartisan, even though I am frustrated with the PS3 -- Blu-Ray is beautiful, though. =)
