Iwata: there are things you can do with cloud gaming and there are things you cant do. We dont agree that cloud gaming is the future and we are trying to work hard on a future where gaming only consoles are not gone. Unified platforms are for us not platforms that are one but rather platforms that have the same development architecture. This also means that there could be more platforms.
Miyamoto: We needed to create new development environments for wiiu and 3ds unlike wii which reused the gamecube architecture. We are unifying our development teams to accomodate this challenge and minimize the losses while preparing the shift. I think handhelds and consoles will coexist as the aim is different.
