Tell us more about these clairvoyant abilities you possess. As things stand, all AMD gets are some cash injections from Chinese joint ventures, and of course their semi-custom console clients. If Zen fails, AMD will have no choice but to downsize considerably, further hurting their ability to make competitive graphics products. No worries though, Roy Taylor and his charlatan sidekick Richard Huddy will just try hard to sell us more re-brands over and over again, pointing out that DX 12 is the future (even though that future is primarily in the developer's hands) and still managing to burn money at record rate.
Realistically, AMD will keep a small niche market (consoles, APUs), but become totally irrelevant to Nvidia and Intel and all the cool things both are pursuing.
