Well, I'm not big on fan club stuff mainly because it is always insanely expensive and often out of reach for the average collector, which is antithetical to what a collectors club should be. Mind you, I am very happy to have my Oktober Guard set from a couple years ago. The collectors club is such a double edged sword. Anyway, I say this merely to explain why the zombies make me happy. It's because I hate zombies!

Never liked them, never will. So the fact that this set is zombies makes me happy because it means I won't have any interest whatsoever in trying to track anything down! So this just means I am not tempted to spend crazy $$, which is good.
I suppose it fits right in with various other outlandish stuff in GI Joe, like Cobra La, Serpentor, ninja BATS, etc. so it fits in the big scheme of things I suppose. But it's just not for me.
As for the 50th, well, I do think that it makes more sense for the 12" stuff to have the direct tie in to that, since ARAH didn't come until 1982. Sounds like the club has that covered particularly by including the 3 3/4 Colton as a nod to the modern era. Funny thing is, I have zero 12" era stuff and really zero interest in it other than as a historical connection to the 1982 line, but the 12" con set might be more appealing to me than the 3 3/4" con set at this point! Ironic.
Perhaps Hasbro proper will have something a little more directly tied in with the 50th with the 3 3/4 line in 2014, and maybe the club couldn't tread on that territory. Perhaps we'll find out in February. Just a thought.
