Abilities? I think they're thoroughly uninteresting and totally
underwhelming hardware.
They're pretty weak. I wish they'd stuck with (multiple) ridiculously high
clocked PPC's personally.

Indeed, they're obviously designed to be cheap this time... or they'd be
better, and more interesting ;)

In any case, it is nice that they're using x86. Seems like a smart

Personally, I think it's disappointing. x86's key advantage is being able
to run crappy desktop code fast.
Games are not usually 'crappy desktop code', they're carefully tuned,
purpose-specific code.
x86 uses MASSIVE amounts of its CPU realestate to tolerate crappy code. I'd
rather use that CPU realestate on more raw power, and put the
responsibility on the engines engineering merits to make the most of it.

This move sets a low upper limit, and the bar will start high. I don't
anticipate you'll see much tier-ing between 1st gen -> 3rd/4th gen games
this time round.

ARM might be better/more interesting than x86, but I actually still think
PPC is a good architecture for the purpose. VMX/SPU is still the best SIMD
unit.
