Yeah, and A8 is not a simplistic chip. Mobiles and tablets now are practically small laptops in terms of power. The latest news were that TSMC are fully booked on 20nm for the whole of 2014. Since most indications show the iphone to be ready until the end of the year, most probably even before September, I doubt they will be fully booked for Apple, the bulk would be ready for the mass sales. And Qualcomm will most likely have their products to compete with Apple. AMD and NVIDIA are even more appropriate candidates for that node since the latest is the venue of the high end (well, also the very efficient nowadays but Apple and Qualcomm are already using it).
The only worrisome thing was that whine/rant of NVIDIA against 20nm pricing more than a year ago but I suspect that's very old news now. They are still their client so I doubt they still have the same relationship.
Let alone AMD confirmed it. They will go 20nm no matter what. Though since they released R9 200 so recently they can't do it before Q1 2015. But NVIDIA can.
