What I don't understand is why Sony and MS fanboys get so upset at the Wii's success.
The DS and PSP have coexisted. I don't see any reason why the Wii, 360 and PS3 can't coexist.
I think it may play out like a US election where the one that sells less (and ultimately drops out of the video games business) will blame the Wii like it's a third party candidate.
In reality if PS3 or 360 fail, it is not Nintendo's fault that did it. It is the manufacturer of the console where the fault lies, for not running their business properly. The PSP may not be selling like the DS, but it is a good product and it's marketed aggressively (advertising, manufacturing, and pricing)
I would cite regulation, but I know you will simply ignore it.
