It seems a little weaker than I'd have figured, but I never really guessed it was going to be even a mild step up, mostly just par.
We've known the CPU is a bit weak for awhile, and while the GPU is stronger, people seem to ignore the fact that it has to draw an additional 854×480 in fillrate to the tablet, unless I missed something, which is pretty huge. Memory seems kind of disappointing, though.
Maybe there's some silver lining to all this, but I didn't actually think they were going to go with a solution more radical than a better dumping ground for their own software and it's delivery. It seems like... another Wii, and that's really what I expected.
