I may pick it up, though not when it first comes out. I won't be running an Eberron campaign, but I may use it for an idea mine and allow players to use stuff from it for my current Planescape campaign if they'd like. I've seen good things about it so far, so the least I can do it pick it up, look at it, and if I think I might use some of the stuff inside for ideas I'll pick it up.
I havn't actually bought a single WotC book all year. I have PGtF, but my players bought it for me for my birthday. Otherwise I won't be picking up much of anything (though I have the Planar Handbook preordered and I'm drooling for it to be released so I can get my little claws on it).
