Perfect! I am really glad you decided to simplify things for yourself and make life a lot easier. Normally it would a headache trying to compare a VLIW4 1536 SP: 96 TMU: 32 ROP : 880mhz GPU clock HD6970 with GCN 1280 SP: 80 TMU: 32 ROP : 1000mhz GPU clocked HD7870 but with Voodoo GPU Ratings, it's already done for you by meticilously looking at PC GPU reviews across the web, and averaging the performance across many games. You could sit there and spend hours trying to find reviews and averaging the performance yourself but you'll end up in the same spot:

All we need now are exact GPU specs of PS4/Xbox 720's GPUs and we'd be able to narrow down the performance and compare it to PS3/360.

7870 - GCN 1280:80:32@1000/1200; 256bits 8770 - GCN2 768:48:16@unkown clocks; 128bits I hope you see where I got confused, even if GCN2 is jump as VLIW4->GCN, 8770 with those specs would need (in my guesstimate) to run at 1.5GHz to achieve 7870 level of performance.

Ya, I don't think GCN 2.0 will be a large jump from GCN 1.0 in terms of performance per functional units, maybe 10-15% increase in IPC, the rest coming from increased functional units and/or higher GPU clocks. A lot of rumors on the PC point to marginal type of increase, maybe 20-30% on the AMD desktop side. It's not going to be revolutionary like going from HD6970 to HD7970Ghz was.
Since mobile HD8900M parts and desktop Sea Islands (GCN 2.0) parts appear to be slated to launch around Q2 2013, we are going to be waiting for their specs. For the next 2-3 months, we'd just be guessing at their specs and probably spinning wheels. With a lot of games launching in Q1 2013, it's probably more productive to spend the next 3 months gaming :) Since AMD will release both HD8900M and HD8000 desktop parts before PS4/Xbox 720 launch, by Fall 2013we'll have all the specs of HD8950M/8970M and HD8750-8970 desktop parts. All the performance of desktop cards will be added to Voodoo GPU power by BoFox and we'll be set for a PS4 vs. Xbox 720 GPU showdown. Since all 3 next gen consoles are likely to have AMD GPUs, things should be pretty easy to compare this time.
What do you guys think about the Hard Drive strategy? Would you prefer a next gen console with a stripped down SKU at say $299-349 with no mechanical hard drive, with MS and Sony giving you an option to buy your own and leaving room inside the box to fit it in? Would be be OK with a USB 3.0 external hard drive like Wii U's move? Or would you rather prefer that all SKUs came with a mechanical hard drive like PS3 does today in North America?
I think I'd actually prefer a cheaper SKU with no mechanical hard drive at all so I could get a cheaper external on Newegg/Amazon and just insert it in. Or I would just use my old 2.5 inch USB 2.0 640GB one which should be good enough for basic demo/game save storage.
