That's 100% guaranteed for 2 reasons:
1) Existing high-end GPUs such as GTX680/7970GE use 190-230W of power. The next round is still made on 28nm, which means power consumption is likely to go up to 240-250W.
2) Next gen's tier of high-end might increase in price from $500 to $900 due to the cost of 28nm wafers + lower yields when fabbing 550mm2 die chips, starting with Nvidia's Titan card:

Sony/MS will not release a console with GPU alone using 200-250W of power on its own and certainly will not put a $500-900 GPU inside a console.
=================================
Found some benchmarks for 3D Ray-Tracing as I seen some people mention that MS/Sony might target this for games next generation:
"The five second clip with 3D Ray-Tracing that we were rendering took about an hour to run" (http://www.legitreviews.com/article/2127/1/)
That we can squash the Raytracing games rumor automatically.

When someone lists out full specs, they list the total # of ROPs and TMUs a GPU has. Notice how they listed 18 CUs for the specs but then listed 18 TMUs. That's confusing and is not how people list GPU specs. Think about it, using the same logic you described, if someone listed HD7970 as a 32 CUs, 32 ROP, 128 TMU card ==> HD7970 would suddenly become a 128 ROP, 512 TMU part...
