Here's a very revealing test:

If you want true ultralight, go for the 13" MBA and save $300. True, you won't have the Retina display, but you might want to wait for the rev B 13" rMBP version anyway.
If you want power for productivity and gaming, and "longevity" in the form of a discreet GPU, go for the 15" rMBP
PS: would've been a better test is they'd used the 2.3 15" rMBP...
