The cost of being an early adopter I guess, I don't really know if they are right or wrong to cater to those early adopter people, on one hand they are marketing this for consumers who want to be first and access some kind of prestige (and it's good for YT vids as well), marketing as purely pro card wouldn't have attracted those people so they did do the right thing, but on the other hand it's giving them a bad name... Nvidia can get away with it on the Titan brand because everyone knows to expect a Ti, that will even be potentially faster but with less ram and cheaper, but because it's a first for AMD everyone is wondering (rightfully so) what the "normal" card will be. It probably wasn't a smart move from AMD to introduce an "in between" sectors card first, I don't know, they tried the "titan" thing and it's backfiring because they lack the mindshare and the credibility to do it.
Maybe they could kill the FP16 and FP64 perf on the RX card, wouldn't that have the potential of bringing better gaming perf ? It would make sense they would do that if it could gain gaming performance, it would also separate the FE from the RX line.
