Nvidia is worth about half as much as Sony and Nintendo, they couldn't afford to do it. Microsoft would never do it even though they could afford it, makes no sense for a software company to buy them.if I where sony or any of big 3 I would buy nvidia instead of game developers. how big is nvidia? I was thinking if any of big 3 buy nvidia they are in a win win situation, nvidia is profitable and GPU for their console will be free
Also, the only reason nvidia is profitable(depending on the year) is because people pay them for the services they provide. If they give out "free" chips for a game console then the company won't be profitable.
