This is nothing new though... Every laptop I've owned (including many PowerBooks and MacBook Pros) has gotten about 1-2 hours when playing a game that maxed the GPU and CPU. How does a ~80-100Watt hour battery get more than 1-2 hours of running a ~40-50W CPU and 30-40W GPU? Physics says no.

I'd be more inclined to agree with you, if my last MacBook has compatible performance. I got easily double the playtime out of my MacBook Pro Retina.
