Those things take forever to come out and often aren't made for a generation. There isn't yet a Fury X Lightning but the 980 Classi was out within a month, IIRC.
I simply pointed out top end cards exist for AMD which is contrary to your claim. Somehow we went from "AMD has no top end cards" to "well they take forever to come out".
But in any case, Lightning cards typically come out 3-5 months after ref board launch (for both teams), which is pretty consistent with the Classified's release schedule, give or take a month. Yes the 980 Ti Classified released very quickly but it's an exception and not the norm, and has more to do with EVGA receiving a lot of flak for releasing the 980 Classified too late for too high a price, and not providing enough bios support. Then there's also the ridiculous 980 (non-Ti) Kingpin which released like literally 1 month before Titan X launch and cost $800, which made a lot of owners upset because again too little too late with too high a price tag. Plus there was a debacle with EK waterblocks when EVGA failed to inform the retail version had a slightly changed PCB layout (one of the caps got moved I believe), and thus anyone who bought the initial batch of waterblocks were SOL, and EVGA simply told them "tough luck" until EK put pressure on them.
980 Ti Classified is also "only" $50 more than the ref card, unheard of for a Classified card. So again, it's very much an odd exception.
Fury X is AMD's Titan so it's unlikely to get anything besides reference treatment. MSI wasn't even one of the AIBs that got seeded Fiji chips so of course no Lightning there either.
