If the latest rumor is true (720 in 2014, PS4 in 2013) Maybe HMC could be ready for 2014. And the high power variant of wideIO might be ready for 2013 on the PS4, as it doesn't require TSV, it is fine with microbumps (Vita).

I think they only need TSV to connect the memory dies together, and it's already being done. They don't need to use wirebond, they can connect the memory to the interposer with microbumps which is a mature process, and much higher density than wirebonding. I mean even the PSP was using that.
You need TSVs to connect the DRAM dies (through the lower ones) to the interposer and you need TSVs to connect the APU/SoC or the whole interposer respectively to the package/PCB (i.e. TSVs in the interposer). And you can use TSVs in an interposer already now (with some additional cost of course), Xilinx does it for their high end FPGAs for instance.
There is no real difference for the need of TSVs if you use HMCs or just stacked DRAM dies with a wider and lower speed interface on an interposer. In the latter case you would omit the lowest logic die of an HMC and run a 512 or 1024 bit bus over a short distance on an interposer and connect directly to the wide memory controller on the APU/SoC die (with micro bumps, yes). You move the function of the logic die in each HMC stack into the APU/SoC and save the HMC interface PHYs. It doesn't touch the TSV requirements other than you lose one die in each DRAM stack.
Maybe it's because they wanted the GPGPU in the APU to work as closely with the CPU as possible using the same memory pool while leaving the faster memory all to the bigger GPU for graphics.
Does the SoC absolutely require TSV to the interposer?
I mean couldn't it be also connected to the interposer with microbumps?
How do you get signals from the PCB to the die on top of the interposer through the interposer? Yes, with TSVs!
Ah thanks, yeah that was the whole idea of 2.5DHow do you get signals from the PCB to the die on top of the interposer through the interposer? Yes, with TSVs!
To which CPU? If it's an x86 CPU, there will be AVX support of course (even Jaguar has it). And an IBM CPU (which appears highly unlikely at this stage) would probably have it right from the start. So what do you want to add?
I was thinking that Jaguar will not have VMX support, but I was wrong.
You are correct. Jaguar does not have support for VMX.
Does it matter how the SIMD extension is called? More important are the capabilities and the vector width.
We don't know that; not at all! We've had one long generation that's been unexpectedly capped with a shift to throwaway technology in portable gadgets. We may see MS and/or Sony planning a progressive architecture, or a 4 year cycle, or a 6 year or a 10 year, or even planning on abandoning fixed hardware altogether after this gen. They may not even have much of a plan for the next-gen and will see what happens over the first two years before thinking about where to go next. I'm pretty sure MS had no idea when 360 launched that they'd introduce a full-body motion controller in its 5th year to rejuvenate platform interest. There are way too many variables to pick hardware based on a business plan.
Recent Sony patent for PS4 controller?

I honestly don't see the rush for 2013 if 2.5D or HMC isn't ready. It's such a potential game changer in my mind it's be stupid to force something out in 2013 just to be out in 2013. Yes people will complain that the gen has dragged on too long some more but you don't want to be on the wrong side fo such a technology shift.

Yeah, but my guess is you'll be waiting until 2015 or later to use those. Then you've lost the generation.
Dont forget this gen has already dragged on way longer than many think is healthy. 2013 will be 8 years of 360 (where past gens were typically 5 years) and sales are falling.
IMO that is a great idea. Cheaper than having to include two seperate controllers.
Final design better not look like that lol.
I don't think they can ever get rid of the glowing orbs. There's just no alternative that would work as reliably. They can be measures from any angle. They remain in view even when not pointed at the tv/camera. You don't need a super-high resolution camera to get good measurements (important for high frame rate input). Unfortunately, image is important and gamers will always shun the "clown noses" for looking dumb, no matter how much better they work.
