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

Call of Duty Modern Warfare 1 & 3, Black Ops, and World at War ran on the Wii despite the Wii having 88MB of RAM to the PS3/360's 512MB.

i don't think call of duty was a good example modern warfare 3 on wii got poor reviews

We are not talking about quality of games but their portability to other systems with less power/resources.
