I'm not a fan of FR, though if a reboot was done I would consider looking at the book (I may even buy it if Elminster is killed off). I would be happy then.
I'd say no it doesn't but it should have at least a single product every two years maybe every three. Just enough so that people know that the setting isn't forgotten.
Heroes of Horror, Libris Mortis, Unearthed Arcana & Ultimate Monsters Volume I and that's all the 3.5 books I own IIRC. I said I skipped the vast majority of them.
I enjoyed it
I liked playing it though I probably didn't play long enough to notice the flaws of the system (or I didn't care) and just wanted to have fun.
