The thing is, the wannabe FR Novel Author fans(which I would call a majority or at the least a sizeable minority of 3.5E era's FR fans) got abandoned by the 4E switch, and FR's bad reputation among non-FR fans as a playground for wannabe FR Novel Authors hasn't been broken enough to allow a full recovery.
We'll see what two more years of 4E novels and two more years of RPGA can do. It doesn't help that 4E Eberron were much better written game books.
Agreed; in all respects 4E Eberron seems to be of better quality than 4E FR (art, maps, appeal to the existing fan base, minimal changes to the setting, etc.).
