We have no idea about Tegra 4's perf/watt ratio. Is it not fair to assume it's as broken as the last three?

We have some idea as it's been debuted in nVidia's shield. :)

Which has a large battery and active cooling. Not realistic conditions for the products Nvidia actually wants it in.

If it was only performance that mattered I'm sure you could put a desktop CPU in there.

I did say some idea, thus not a definitive one.
Shield is also aggressively clocked, so one would assume that lower clocked variations of the chip would be better from a performance/watt ratio.

Besides, nVidia has once again licensed a complete ARM (This time the Cortex A15) core, it's not a derivative of the architecture that other ARM licensees might do, so whatever Pro's and Con's the A15 has, the Tegra 4 will have.
We won't see nVidia do it's own take on the ARM cores untill Project Denver arrives which is when we *should* see some big gains in every area.
