If SCE gave up on consoles and sold all their IPs to Nintendo does it make a sound?
We've seen many, many children heal. We've seen midgets grow. I don't make this stuff up.
Mario Something, Mario and Luigi Something, Luigi Something, Zelda Something, Metroid Something, Starfox Something, Pokemon Something and Wario Something
Would I be interested? Naaaah.
Would Mario and Zelda games then be the best selling games on PS3/PS4?
Yes. But thus far they seem to be able to stick to making consoles, even though they are out of date by comparison. They make solid handheld systems though, so it's unlikely they'll go out of business anytime soon.
