That's not true, actually. It was a fairly weak CPU by 2005 standards, not comparable to Intel's/AMD's best models at all.
Wait, what ? Xenon a weak CPU ? Next thing you'll tell me will be that every netbook in 2006 had a Cell equivalent !
When I'm talking about consumer level CPU, I'm talking about Pentium, not Xeon or Itanium...
Please, show me a Pentium available in 2005 which was faster and more advanced than Xenon. The 999$ top of the line at Intel was a 2C/4T Pentium at the time...

I think that this pie chart might not be a good indication for next-gen though. A lot of things are different now.
IMO, it's very likely that they'll try to get the GPU and CPU on the same die right from the start. They could save a lot of money by doing that.
We always assumed that if Microsoft go the Fusion route, they will take the whole CPU+GPU package but maybe they'll just get a modified GPU which could be put on an IBM CPU die. The 360 Slim showed us that getting a GPU and a CPU originating from two different company on the same die wasn't a problem.
Beside, they'll probably want to get the smallest chip possible at release because future die shrinking (16 nm and 11nm) could prove to be more difficult, GlobalFoundries had their share of problems with 28nm IIRC.
The cost of memory won't be the same too as GDDR3 was rather new in 2005 and clearly wasn't as widespread as GDDR5 is now, let alone in 2012/2013.
One of the reason why I think 4 GB is more likely than 8 GB is because there will be more expensive things bundled with the Xbox 720/PS4 compared to the Xbox 360/PS3. Kinect and Move will probably be standard along side a traditional controller. Ethernet and composites cables will most likely be on their way out to make place for an HDMI cable and integrated Wifi. All of those things will be additional costs, some of which won't be reduced as easily as the CPU+GPU cost IMO.
Oh and it can't be said enough in this thread, you can't compare DDR3 with GDDR5/XDR2. The later are much faster and more expensive to produce than the former otherwise we would all be rolling with 4 GB of GDDR5/XDR2 as system memory...
