I predict soon...
a PC form factor based on AMD CPU+GPU on a chip, 8 GB RAM on the same chip and a 10TB SD-whatever RAID 5 array, an as yet unannounced mini-jack-to-128-USB-port-expander-cable and a HUGE power connector for a power brick cable. The 'pro' model will have 128 SD-whatever slots for storage expansion on the underside of the case.
It will look like this: a two foot tall by one foot square passive heat sink with a one cubic inch slab of vitreous enamel stuck to the bottom encasing the silicon.
Case vendors will be reduced to competing in terms of the shininess of the surface finish of their heat sink or the air resistance of the add-on product legs to lift the beast off your shag carpet. PSU makers will try to compete on the aesthetics of their PSU bricks. Both sectors will soon become bit players when punters realise that "it's just a power brick, mate!" and "it's just a heat sink, you wanker!".
Shortly after that the LCD vendors will offer 42" LCD screens with heavily knurled fascias to dissipate the heat from the one cubic inch of vitreous enamel hidden behind the screen. Soon followed by n*7" screens where n is an element of the natural numbers greater than six.
Soon after that Intel will offer a completely pre-engineered solution with 1/5 the CPU power and 945 graphics but marginally lower cost of production of finished product. All the names will switch to the Intel solution. AMD and it's ecosystem will vanish into the depths taking a massive swath of value owned by true believers with it. As a result average resale value of houses will drop by 10 per cent. A flame war will ensue on USENET about the good old days.
Every market player but Intel will be left to compete based on the quality of their industrial design and universities in Europe, the Americas, Japan, Taiwan and China will eliminate their science and engineering faculties in favour of faculties devoted to teaching how to design pretty things.
Apple, seeing the gates of hell open beneath it's feet, will sue everyone and everything in sight for patent infringement for offering an all in one vertically oriented form factor PC. A religious war will ensue on USENET.
Seing this, and the intrinsic likelyhood of revolt, the US Congress and EU whatever and Chinese politburo will all fund research into sounds that can kill from a distance.
The Internet will melt down under the pressure of the wars and blog posts about black sound projects. Microsoft will emerge supreme because online software provision has become impossible. Google will, with the failure of the Internet, fade into obscurity and it's share price will fall so low that the exchanges de-list it. Debt value removed by the failure of Google will push the current market crisis over into total destruction of the capitalist system. Microsoft hegemony will encourage and ultimately complete the transition to purely corporatist economics and politics. The last vestiges of the democratic dream will fade into the background noise of the gnashing teeth of overclockers and the howls of disenfranchised Starbucks customers. Without open markets finally Microsoft will collapse, unable to sell even DOS 6, as consumer cynicism sinks to 1980's era USSR levels.
At this extremity the rump capitalist and technological polities, having no consumer disposable product markets to sell into will be forced back to the old standby mechanism of weapons production. Global tensions will rise until WW III breaks out. Billions will die. With only a few hundred million people left our outer space overlords, knowing all along that humanity was way past sustainable population overshoot for the past 50 - 60 years, will step in and make all the weapons evaporate.
Karl Marx will then emerge from his crypt and establish a knowledge worker's paradise on earth. And at that point in humanity's history, for the first time, all first person shooter games will work equally well on all the available GPUs.
There will remain, however, in a sort of echo of the past glories and desperations, a heavily suppressed and deeply underground activity designing new samizdat cores based on a fusion of old nVidia and ATI ideas. Under the pressure of intense state and social censure great and terrible risks will be made: as a result and at the cost of many chip designers' lives GPUs will finally surpass x86 CPUs in general programmability, CUDA and CTM will be subsumed into OpenCL, which will lose the need for contexts.
A renaissance will slowly arise from the many years of blood and agony and muck of of disappeared graphics chip designers. It will be driven by a new computational model: a reformation based on GPGPU computation will take hold. Computers will become truly visual, and we will be able to frag with *both* realistic physics for the virtual shell casings *and* photorealistic gore splatters.
I give you the theory of dialectical fragaliciousism.
