I fade in and out, honestly. I'm actually looking more closely now, but only because I'm late into my Epic 4e game and not quite onto my 13th Age game, so there's a gap. Besides enjoying reading and sometime chatting about game design anyway, I'm looking for stuff to lift and bring into my 13th Age game.
My groups have already expressed pretty much no interest in converting to the new edition, though I'll give it a whirl as a one shot. Frankly, I think most of them dislike 1e/2e (save one or two), hate 3e (save one or two), and enjoy 4e (save one or two), so talking about a modular edition with influences from all is largely a losing prospect. I think they're just tired of the D&D/PF kind of set-up and assumptions. We'll see if 13th Age scratches the itch. If not, it's comforting to know at least there's a massive selection of games out there.
Has Wizards handled this properly, though? Eh, there is something commanding about a finished product, or nearly finished product, that inspires confidence and authority whether or not you agree with every aspect. It's the edition and that's pretty much that. Seeing a game form from the ground up via playtests, but two phases behind what they're actively working on, and with different concerns addressed in different packets dilutes any enthusiasm I have. I can't say I'm excited with some of their intended decisions, either, like Forgotten Realms 5e coming out the gate, but that's my preference getting in the way.
