I don't expect next gen consoles to out perform my CPU or RAM, but I do expect better GPU performance than my 7870 by the time the neXtBOX launches.

Mostly likely will not happen, 7870 1ghz+ has a higher TDP then 175w, which means higher costs because power requirements and cooling needed. Dont expect more then a 100w TDP based gpu.
Yeah , it will happen. Want to Pay Pal bet on it?
HD 7850's die size already smaller than 1st gen NVIDIA RSX.
---
1st gen NVIDIA RSX = 258 mm^2
1st gen IBM CELL = 230 mm^2
Total: 488 mm^2

Option 1
AMD Radeon HD 7850 (16 CU GpGPU) = 212 mm^2
AMD Trinity (6 CU IGP) = 246 mm^2
Total: 458 mm^2
---
Option 2
Semi-custom AMD Trinity (quad core PileDriver) with Radeon HD 7850 = ~335 mm^2
Quad core PileDriver = ~50 watts (with 4th core for yield issues).
Radeon HD 7850 = 130 watts (16 CUs operational, with 4 CUs disabled for yeild issues).
Total: 180 watts.

Based on 1st gen PS3, power consumption can be around 209 watts (e.g. FF13) i.e. PS3 used 380 watt power supply. Option 2 is possible for PS4.
Option 2 wouldn't match Intel Core i5/i7 Quad-Core with Radeon HD 7950/7970 or GTX 670/680 based PCs i.e. on the GPU part, the relationship would be like Xbox 360 vs Geforce 8800 based PC.
Radeon HD 8850 is estimated to have a die size of 270 mm^2 which would make it larger than 1st gen NVIDIA RSX. Older parts (e.g. 7850) would have less premium than newer parts (e.g. 8850).
Radeon HD 88x0/89x0 has been delayed until CES 2013 with actual release around June 2013. Sony has the tendency to use older design.
MS has the tendency to use newer design with smaller die size/lower max power than Sony.
