I think Wii U can easily achieve 1.48Ghz while the maximum I can think of is 2.48Ghz.
GPU boost from 550mhz to 800mhz is achievable while I would realistically expect to be boosted to 650-725mhz.
If this rumor that has no source and any validation comes out to be true then I can bet you will see more 1080p games, Wii U already has one and that is Rayman Legends and with the boost like this there will be some 1080p games with simple 3D graphics even thought Rayman Legends is 2D/3D.
Lets look this from a logical perspective... We don't know all the details involving Wii U's CPU and GPU nor what Nintendo's plans involving Wii U but it seems it will be somewhat similar to DS that after couple of months the OS was seriously streamlined thus more RAM available and a locked core was unlocked for developers.
You can't directly compare two CPUs with different architectures in terms of clock speeds and the heat generated or power requirements. The comparison is useless.
The only useful thing you can infer is that, if true, Nintendo intentionally under clocked their console at release by a massive margin. And that they massively improved performance in one fell swoop and didn't bother to tell anyone.
Personally I don't think Nintendo are that dumb. They released a patch that improved the OS, apparently it makes a few games smoother. That's it.
At the end of the day someone measured power consumption with a watt meter, it hasn't increased. Not even Nintendo CPUs run on magic.
