Just want to point out that risk production doesn't necessarily mean that it is more expensive, they would be getting wafers for the same price as mass production, it would just mean that they are taking a slightly larger risk than usual that yields will be acceptable on the process with their design. This would mean either they have a near perfect design for the process or they have built in more redundancy to negate the effects of the new process.

Still finding it pretty hard to believe that the 20nm rumor is getting so much traction. I still find it highly unlikely but not impossible.

FYI- There was always a new product launch planned for 2H '13... Some people just didn't want to listen, looking at you Sky.
