All consoles this generation are featuring GPUs by AMD, and Xbox and PS4 have even APUs by AMD. The upcoming more powerfull revisions of the PS4 and X1 as well the NX which will also feature all GPUs and CPUs from AMD.

This means that not only will consoles have one single AMD hardware for a given generation but just like with Graphicscards consoles will feature the latest GPU and CPU updates from AMD. Meaning that AMD will get quite a lot of money for its latest APUs who wont go down in price, this money can then go into R&D to make even better hardware for consoles and PC. And because BC will be imported from here on out, there is no chance for Nvidia or Intel to give them an alternative.

I think Nvidias greed is what killed their console bussines. First they didnt want to go down in price for the original Xbox GPUs as MS signed a shady and dumb contract. And then they gave Sony a mediocore GTX7800 for the PS3 instead its latest GTX8800. I think Nvidia will have a troubled future espacially if consoles can replace more and more the PC space with hardware revisions. Same could be true for Intel but i think they werent too greedy they just didnt cared.

Opinions?

My opinion is that Nvidia will be just fine without consoles. It's AMD who have to prove that they can run a successful business and it's upon them to catch up to the market leader.

If they suddenly catch up in market share that just means I have to buy more Titans.

Yeah. AMD were desperate and in return provided Sony and MS an excellent service. Basically bent over backwards for them. I presume they're being good to Nintendo too

And considering their success so far and the possibility of years of good service they will probably get first dips on the successors if they offer an appealing product for the next gen.

With AMD making CPU and GPU they are just the better choice.

They were the better choice because of price. An Intel-Nvidia setup would've worked just as well but probably twice as expensive.

Dont the AMD APU and GPU work together to get maximum performance?  I think this is the setup that Sony, Microsoft and Nintendo want.

Intel APUs are not nearly as good as AMDs.

"AMD will get quite a lot of money for its latest APUs who wont go down in price, this money can then go into R&D"

What is basis for claim that AMD's APU for Sony/MS/Ninty won't go down in price?
Fabrication cost is external to AMD, so quite easy to factor price drops into contract... Or by benchmarking to market rates, etc.
I mean, you contrast AMD to NVIDIA who insisted on fixed contract price to MS, yet now claim that AMD is doing the same and it's good?

"they gave Sony a mediocore GTX7800 for the PS3 instead its latest GTX8800"

I think that can be translated to Sony bought a mediocre GTX7800 equivalent instead of latest GTX8800.  
Where is AMD selling their latest high end GPU to ANY console manufacturer?  PS4.5 is not impressive in PC space.   So why hit NVIDIA for the same?
Console manufactuers don't want to buy the latest high end power, and they get exactly what they purchase.

"I think Nvidia will have a troubled future espacially if consoles can replace more and more the PC space with hardware revisions. "

If your fantasy of GPU OEM's magically giving away high end APUs to consoles happened, that scenario might make sense.
As is, hardware revisions ala PS4.5 just mean console can match low-mid-end PC GPUs at the point they refresh evey few years,
with higher end PC CPUs/GPUs always dominating and low-mid-end GPUs overtaking consoles before they refresh...
And PC CPUs tending to consistently dominate console CPUs even at console introduction time, CPU limitations in games are real.

BTW, you seem to have left out NVIDIA's lucrative GPGPU/HPC business, what's up with that?

IF you scale back scope of your claims, then OK, the console business has helped AMD stay in the game.
Going forward, it's possible they can compete more with NVIDIA 1:1, not possible if they went under/focused solely on low-end/etc.
AMD's ACE approach certainly seems to be worthwhile (most leveraged by Sony), albeit NVIDIA's GMU may well catch up in future. 
You seem to push your claims into grandiose irrational territory well beyond that though.

well, as i look at PC requirements, i often notice AMD needing higher specs. now that you bring it up, i feel like Nvidia parts would make console cheaper and easier to optimize for.

What Vivster said could not be more correct ...

They need to find a way to translate that console dominance into dominance in the PC space as far as GPUs go ...

Pretty much this.

And if I recall correctly,they had financial problems so I guess they cut Sony and msoft a better deal.By better I mean cheaper.
