Batman: Noel deluxe hardcover
You can pick up the hardcover now or wait a few months and get the trade paperback. Since the hardcover is deluxe sized and the trade likely will not be I'd suggest ponying up for the former if only to see Bermejo's art in the largest format possible.
Joe the Barbarian hardcover
I've been waiting for this book for well over a year and can't wait to get my hands on it.
Kieron Gillen is an excellent writer and while I haven't followed the X-Men franchise as closely as I was a year ago I'm really interested in the current goings on of the series. The team has split into two factions, one lead by Wolverine, the other Cyclops. Both this title and the Wolverine and the X-Men one have fantastic creative teams. This one features Carlos Pacheco on art. Pacheco is one of my personal favorites and though I haven't been blown away by any of his Marvel work, I'll still read anything he draws.
Will I buy this in single issues? Long term, probably not. I'm a wait-for-the-trade guy with Marvel for the most part. I'll definitely be picking up the first few issues of this though. Not only is it written by Gillen and drawn by Pacheco but it features the return of Mr Sinister. My favorite X-Men villain!
