Of course XboxOne hardware optimizations and cloud will do those high-PC outdated in a pair of years.
(*) The hard part is to compute the performance gain introduced by the custom components found in the consoles and in the cloud system. The cloud offers a theoretical 4x boost for the Xbox One, but nobody know how many of that theoretical performance will be finally used by the games
Uhhh...no, since Etherent (not even the connection; the actual ethernet link) would become the primary system bottleneck. Anything relying on external access will slow down your processing.
But they plan to use the cloud for tasks not affected by latency and bottleneck. Of course the real improvement in performance will be not the theoretical 4x, but the cloud will not slow down processing. Microsoft already showed demos of games using cloud.

Intel isn't ignoring HSA. Their drivers have been upgraded for Haswell and perform quite well now for compute. It's one of the more shocking things about Haswell. Their OpenCL performance of the HD4600 is faster than the A10-6800K.

Intel is not member of the HSA foundation and has no plans for HSA support in any future chip, so far as I know.
OpenCL is not HSA. OpenCL is a mere interface to access the GPU in your computer for non-graphic tasks. HSA is about blurring the traditional distinction between CPU and GPU.

Look at the PS4 APU. Most people think of it as a 8-core CPU plus a given Radeon GPU, but it is something new. There is no real distinction between CPU and GPU at the software level.
It is the programmer who splits the APU into a CPU and a GPU and this split is dynamical. You can use the CPU to assist the GPU or you can use the GPU to assist the CPU. This is very related to the claims that the PS4 has not bottlenecks.

And in other news: The HSA chip will drive software development so much, the XB1 at least was demoed on a Win7 PC with an Intel CPU and NVIDIA graphics.

The irony might be as bad as the XB1's pre-sale numbers.

The irony is that some demos at E3 were running on real Xbox1 whereas others run in a high-end gaming PC with a GTX-780. This seems to confirm my prediction that the minimum PC for matching a next gen console is a i7 + GTX-780
