So what we can take from this roadmap is that we won't be seeing anything new in desktop GPUs until early 2015. I like it because people won't have to upgrade so fast. And this also means that the step from Kepler to Maxwell will be huge and I hope they don't disappoint us with a mere 10% increase in performance.
I don't think so. Especially amd i dont think they want to keep 7970 as their main flagship until 2015. In performance perspective there might be no reason to come out with much faster gpu because the performance are quite excessive even for now but it doesn't mean the competition will hold back.
