From what I've seen most Haswell chips are just bad.
1.3v to 1.35v on air is still possible for most with top end air or closed loop cooling solutions.
The problem is they're getting garbage overclocks 4.3-4.5GHz with that voltage. I don't even need 1.3v for 4.8GHz, seems the quality of chips coming to desktop for Haswell is leaving something to be desired.
Actually, reading OC 4770k threads elsewhere, we get a tad better than that. Vcores are coming in lower for 4.3 to 4.5GHz. But you're right on the second half: 1.35v will not quite cut it for 4.8GHz. Overall, though, Haswells are not doing as badly as you make out. Especially when you factor in AVX2. It heats up a chip even more than AVX.
But then, you're restating a reason for the 6-core cpu's: soldered ihs to facilitate better cooling. And by next summer, Haswell silicon should be fairly mature, so the only real silicon lottery at that point should be whether you get a center chip or an edge chip.
