They are trying cookie cutter development for these consoles. This is an issue, and will be for the newest generation of PS4 and X1 as well. The clock speeds of all 3 new consoles are lower then what we are used to seeing. That doesn't mean that they are weaker, it means they are different. Also, clock to clock on different platforms is very hard to compare because there is no baseline or equivelancy to compare. Developers are going to have to learn to use eDRAM to it's full extent on both the Wii U and the X1, as well as learn to use multi-core systems which they have been very bad at so far on PC and consoles alike. They might be able to continue to do this with the X1 and PS4 in conjunction, however there are enough differences between the two that if utilizing their strengths it will make vast improvments to performance. The same can be said about the Wii U as it's a very different architecure with extremely low latency. I'm not going to say it's on par with the other two, because that is extremely unlikely, but to see it's true potential a developer will have to learn to work with the hardware.
It's a similar thinking to comparing AMD/Ati GPU's to Nvidia. Nvidia takes a brash and brute focus with their GPU's as AMD/Ati takes more of a finesse approach, but both have their pros and cons.
Gotta figure out how to set these up lol.
