How will the Wii U fit games on the PS4, if the PS4 will have 7GB RAM available?

Graphics are scalable the Wii U would only get in trouble if physics ai get to such a high level that the core gameplay somehow relies on Power/Ram.

Aslong as the devs will just use the Ram for cosmetic stuff Wii U will not have a problem.

But that doesn't even matter I doubt we will see many AAA 3rd party games on the Wii U so its not really a problem.
