OK, I might have exaggerated a bit, but wast majority of PCs sold use IGPs. Us enthusiasts are very much the minority and it has always been that way.
I will believe Broadwell GT4 can do 2Tflops when I see it. That'll require between HD7850 and HD7870 level performance, and I just don't see that happening. Lets say they double the number of EU's from 40 to 80. That times 4 equals 320 shaders more-or-less (rough simplification). Even the 6800K has 384, the HD7850 has 1024 and the HD7870 1280. Then you have a very nasty bandwidth problem even with 2133MHz(34.1GB/s)/2400MHz(38.4GB/s) DDR3. I haven't seen that many notebooks with 2133 and higher RAM, but if we keep to desktop the HD7850/70 has 153.6GB/s available...
About stacked memory its still a while off for actual shipping products, and no one is stopping AMD/NV from using it with discrete GPUs. I even think I saw a roadmap somewhere where Maxwell's successor (Volta or whatever it is called) used it.
And the problem will also be price. Look at GT3e. Where do you actually see it? Very rare except for Macs, and it is expensive as hell. Pretty much everywhere else you get cheapo HD 4400 or HD4600. I know there are exceptions, but it is really disappointing to see Intel making so much progress with integrated graphics and putting the low end solutions in most applications.
Also, regarding Broadwell, even if they can get a really high number of gflops, that does not necessarily translate into equivalent improvements in real world performance.
