It's an interesting array this year, with someof the usual suspects missing and some very strange choices for inclusion.
Probably the pick of the bunch for us would be the Maggotkin of Nurgle Battleforce: Shudderblight Cyst - yes it's Nurgle and eeeeew, but this is actually a very clever set which someone actually thought about, especially adding the Rotmire Creed from Warcry as a cultist support element. Very cool and a further sign that Games Workshop (sadly) loves Nurgle! Other sets include the Flesh-eater Courts Battleforce: Charnelgrand Jury (including the new Cryptguard minis), the Ironjawz Battleforce: Wrekkamob (a faction we see very little from but have a great selection of minis, including the rarely seen Maw-grunta), and the Cities of Sigmar Battleforce: Founding Foray (which gives you a pretty good cross section of the shooty and impactful elements of the Cities of Sigmar range).
The Warhammer 40k boxes this year are a little less exciting, but the Dark Angels Battleforce: Inner Circle Task Force does come with a Primarch and the Inner Circle Champions (which is almost always out of stock). The other sets include the 400th incarnation of the T'au Empire Battleforce: Retaliation Cadre (again showing GW really don't know what to do with the Tau), the Adepta Sororitas Battleforce: Penitent Crusade Host is quite smart as it gives you transports for your troops but isn't too exciting, the Necrons Battleforce: Hypercrypt Legion includes a bloody C'tan Shard of the Void Dragon (and like the Tau, shows GW really have little if any love for the Necrons in what is a pretty boring box), and finally for 40K the Imperial Knights Battleforce: Valourstrike Lance which is a nice way to get some Armigers, but with only one transfer sheet, there probably won't be too much uniformity in how they look.

In books this week, the new incarnation of Eisenhorn: Malleus – Illustrated and Annotated Edition in Hardback in all it's glory is on pre-order, as is the paperback versions of The Ghosts of Barak-Minoz and Skaventide (and wasn't that boxed set yet another disasterous release for Age of $igmar).
