Don't trust AMD Roadmaps so often particularly the Enterprise/Sever roadmaps.
I agree with you that it is not a good idea to trust AMD roadmaps, but I don't think this leak should be completely discarded. Each roadmap revision AMD did brought bad news, we got either delays, or cancelled and watered down designs, never a revision for good. So this roadmap indicates the best case scenario for AMD.
I'm eager to see what AMD is going to field in 2014. When Intel launched SNB-EP Intel toasted AMD server business because the chip was much superior to Bulldozer and 32nm was already very mature and winding down on consumer so they could fill all the relevant price points. We are going to see the same in 2014 but in a much worse fashion. Intel launching Haswell-EP on a very mature 22nm process against whatever AMD throws at it on 28nm.
