I've said this before and will say it again. The Wii U is 3-4 times more powerful than the 360. 3-4 times more powerful does not mean that games will look 3-4 times better, it doesn't work that way lol.
You've got a CPU with 3 times the cache (plus access to at least 32MB of eDRAM which as I've said is huge news), a GPU with more than 3 times more eDRAM with both read and write access unlike Xenos, 4 times more RAM, a CPU that isn't hampered by dealing with sound, IO and OS functions, a CPU that has half the stages in its pipeline and a CPU that's out-of-order as opposed to in-order.
The fact that we've seen the launch multiplatform titles running without any serious performance issues speaks volumes - those titles were ported from consoles that have a completely different architecture, in-order processing and SMT and as I've mentioned having v-synch enabled for most of them also gives an indication of the Wii U being a fair bit more powerful.
We'll get more of an idea what the console is capable of when we see Watch Dogs which is ported from the PC SKU along with the PS4 and One SKUs which share a similar architecture. You've got to remember that ports from PS3 or 360 code, thanks to the consoles' architecture, are CPU heavy - the majority of floating point work is done by Xenon and the Cell - and games coded for all 3 current gen consoles will be GPU heavy, the majority of floating point work will be done by the GPUs.
