The power difference between PS4 and Wii U is not that significant. Of course the PS4 will produce better graphics, but the Wii U is capable of toned down versions easily.
Only very physics heavy games could be hard to reproduce on Wii U.
But there is also the other way round: Wii U with its unique hardware design and fast connection of CPU/GPU and eDRAM could some things easily that would take an enormous amount of cpu/gpu power on PS4.
