Why only 2K? We already can do 4K at 30fps with ~4tflops, can we?
PS5 with at least 10-15tflops (and better technology) will obviously target 4K (and easily IMO) for gaming and movies, exactly like PS4 targeted 1080p for games and succeeded, we still have only one game sub-1080p, an unoptimized launch game at 900p and at 60fps).
I really hope that Microsoft understand that and really try to release a 4K hardware this time. The problem with XB1 is not really the Tflops but more the inefficiency of the API (directs X is the culprit), the bad memory architecture (just see what Sucker punch can do with a ~100MB fast video framebuffer with Infamous SS) and number or ROPS.
What they could add this time is a hybrid SSD hard drive to improve IO access.

Teraflops aren't important.
Compare the Radeon 5870 against the 6970, the 6970 has a slightly lower TFLOP number, but the 6970 is easily faster, both despite having more flops than a 7870, looses to the 7870, see the trend here?
You need SERIOUS horsepower to render games at 4k and beyond, my old three Radeon 7970's in crossfire struggled in many games at max graphics at 7680x1440, that's roughly 20% more pixels than 4k.
Now I have Quad-Radeon 290's and it's no longer an issue, not because of the "Flops" but because of the video memory amount and bandwidth, an extra card helps a ton too.
This level of performance is not going to be mainstream performance anytime soon.
The GPU upgrade cycle has also slowed down in recent years, no longer are we seeing giant leaps and bounds every year, it's shifted over to bi-yearly.
You would more than likely be looking at a QHD standard for the next consoles, that's 2560x1440, which is a resolution that's gaining momentum across mobile and the PC industry.

Tflops are still the best way we have to compare consoles. It's not perfect, of course but it works very well IMO. Just look at the similar number of Tflops in very different technologies, if you add CPU + GPU with X360 and PS3, most recent games reached a good parity (GTA5) like the number of total Tflops would have told us.
A good another example would be the Wii-U but I won't go further here...
About 4K, a 4 Tflops card is already enought to have a locked 30fps in some 30fps multiplatforms games already like NFS or Batman. Just imagine what a better tech and 10~15tflops could do.
And crossfire tech is innefficient and shouldn't be used as a reference.
