talk about reading comprehension fail I said Tesselation as shown in the Samaritan demo, tessellation =/= Samaritan demo. Tessellation is a technology that allows more detailed geometry to be procedurally generated on the fly which allows more complex models to be shown with less of a performance hit and less work from artists, it also allows for procedural water geometry and dynamic damage models among other things. The Samaritan demo is just a widely known example of a use of the technology in case you weren't familiar with the tech. 

here are some examples of it's use

As for next gen being able to run the Samaritan demo yes it will because that is what Epic have set the bar at and just like the 360 doubling the RAM at least MS will go out of their way to make sure that they keep Epic happy. The demo with everything turned up to 11 at 60 fps 1080p unoptimised on windows may require 3 GTX 580 to run smothly but once it is hard coded and optimised for specific hardware it won't even need a 5th of the prcessing power even less if they drop some of the tessellation and AA and go to 30fps. Add in the fact that MS&Sony won't launch their consoles before late 2013 so they will have access to GPUs 2-3 generations beyond what is available today and you shouldn't even have to go above the 360's TDP and as long as they don't use any exotic tech like Cell prccessors, next gen disc formats or RAMBUS memory then is shouldn't cost to much ether. 

Next gen MS/Sony consoles's will be a big jump because as I have said before they have no other choice as graphics advance you need bigger jumps in power to push resaults that are noticably better. That is the reason many people think that this generation was a smaller jump in graphics than the last jump and why some people fing the Samaritan demo unimpressive. And if the casual observer can't tell that there is a big jump in the level of games that can be played then there is no reason to launch a next gen console. If you ask if people if they want next gen consoles most will say no and that they are happy with the PS360 and to convince people that they need to upgrade to the next gen they will need to see something amazing. That is why 2013 is the soonest we will see MS or Sony's next console because they are waiting for the time when they can affordably make a jump in power that will make Uncharted 2 and Gears of War 3 look crude and last gen.

Rumours on 1080p have been mixed at best and them not fucusing on 3D means they won't push for it at least at launch so IGN talking about the hardware's 3D capabilities is stupid that was the point.

A console GPU is no more capabable then a desktop counterpart with the same specs it's just that being able to directly access the hardware and tailor software to the hardware means the developers can get better resaults. And while Nintendo could spend a lot of money retooling a R700 core to add features like Tessellation but that would be a stupid waste of money considering that there is a pre exisiting proven GPU core design already created that is more power effeciant and supports many more features (most of which would be cut for a console tho as hardware video transcoding isn't an important feature on a console) if they wanted the extra tech they would have used a R800 core they didn't and they haven't.

Actually the bottom end is half as powerful on paper the 360's GPU was a beast at the time ahead of even high end GPUs at the time. 

they won't use any specific card they will use a custom chip bassed on the R700 architecture and there is no knowing how powerful it will be exept for the rumours I have already pointed out. 

Yeas because the PSP being may time weaker than the PS2 and Wii stopped all those sports games being ports of each other and games like Grand Theft Auto: Liberty City Stories and Silent Hill: Shattered memories eh? I am not saying they will look the same or run the same but games can still be ported even if the NGP version is down resed doesn't use AA and has smaller draw distance and the PS3/Cafe version has a lot of extra content...

I'm not saying it's impossible, but I dare to say the chances are pretty slim, most likely Café will use a special interface again, how are they gonna port this?

Depends on the interface and how integral it is to 3RD party games, currently rumours suggest that the system will feature standard controllers with an added touch screen, now the NGP has all that covered, the NGP even has accelerometers and gyros. Of course we are bassing all this on rumours and speculation which could be wrong and the Cafe could have something wild like brain interface or something but I doubt that that would eb the only control option in any case. could be that no retail Cafe games are also on NGP but that some games are download only on the Cafe and also on the NGP in some way, or the very real possibility that there will be none for what ever reason.

Marginally higher resolution and similar framerate using similar assets is "half the performance"?

Beyond that, the low end GPUs are not meant to play games ... They're mostly designed to be used in business class desktops and ultra low end PCs. Which is another reason why Nintendo would never choose one of these processors as the base of their next generation system.

Cod 4 is a 60fps game on consoles dude 

Also the HD 4850 only has 4* the shading power of the Xbox 360 on paper. Xenos is about equivalent to a ~200 Stream processor GPU.

actually on paper the Xenos 4GP/s pixel fill rate and 8GT/s Texture vs the 4850s 10GP/s pixel and 25GT/s texture which puts it around 3* the shading power on paper, of course that is only a small piece of the picture as the 4850 is capable of DX10.1 shaders so can do certain effects much faster.

Oh my god. Why are people so quick to assume that Nintendo cannot build a super console? We are talking about the Grandfather of gaming here. Nintendo can build a console that rivels MS or Sony at any given time. It just comes down to price and what people can afford. Laugh all you want, but in 23 days we will all be blown away by Cafe. This is all part of Nintendos plan, build a massive user base and then bring them over next Generation, Nintendo doesnt need profit this Gen, they profited since day 1 with the Wii. Cafe will be the first console to offer true 1080p, steroscopic, games with massive 3rd party support.  This will NOT be a Wii. This will be a console for the "Hard Core" gamers. It WILL rivel what MS and Sony have to offer. So diss Nintendo and put them down all you want, people like me who are saving their money now will be playing an amazing console with amazing games. While you wait for a console that will not offer much more.
