I can only see a company like Google or something, I mean from a sector we don't have a company yet.
We have Nintendo as a company from the traditional toy and games sector, we have Sony from the electronic devices sector (while many others from that sector had a try and failed) and we have Microsoft from the software applications and PC and whatever they also do nowadays sector.
Apple is something like a hybrid between Sony and Microsoft when it comes to sectors they're in, so I don't see them entering the market as the other two haven't handled so great money-wise.
As for EA, I don't think they would be successful... I mean, imagine a console that consists only of EA games! Also, they had to do much more quality control. Maybe they'd have a chance if they teamed up with another third party that is better in the single-player games sector. The only company that comes to mind (because it would never be a japanes company) is Ubi Soft, another company that is known for games with low quality (amongst great ones of course).
