And really barely read new epic fantasy anymore, really - though I'll finish Martin, when he finally finished his series.

So can't really comment on that part. But more generally, if the long delays in WoT and aSoIaF have pushed their fans into other genres and gotten them to read other things too, making them more relaxed about the wait, that obviously can't be a bad thing. And I must say I'm curious about how the unique aSoIaF situation will play out - will the series' fans get their "own" conclusion at all, or will they have to be satisfied with the increasingly different TV version?

I do get the impression that epic fantasy as a genre is moribund, though. Several promising starters have suffered delays as bad as Jordan's or Martin's (Rothfuss, Lynch), and today's younger generations, if reading at all, are so swamped in specifically YA fantasy (or vampire romances) that they have no time for anything else. Besides that of course there are also people publishing stuff that is simply more varied and less easily caught in a label, that part isn't a bad thing.
