I think MicroSoft will be the next, maybe Sony, but I doubt it. The reason I don't think Nintendo will be the next is that they don't have anything else going for them. They earn money from making games and systems where those games get released. MicroSoft is a big company that will probably quit the console market if they see the market gets too rough to go on. They got the PC market, they got the tablet and smart phone market, though I wouldn't want a Windows phone or tablet, they have that going for them. Sony got multimedia. They got Hi-fi systems, they got decent phones, media players and some of the best looking TVs out there. Sony could give up on consoles today and still do pretty well without it. Nintendo would sink away without the console market. So I am voting for Nintendo because they're the company with the least wheels turning.
Oh yeah, I got the opposite way of thinking today. Boom!
