Haven't been paying much attention to 2nd ed DH. I did get a game of 1st ed though, a VOIP one with some of the guys in my Planetside outfit. We learned that walking into plasmagun fire is Not A Good Thing, and our Arbitor may be looking at a new set of bionic legs to go with her bionic arm. At this rate she'll have more augments than the Tech Priest soon. 3 of the 5 characters got set on fire, my Adept had a read of a very interesting book on deamonology and has gone slightly more insane than he already is :)
On the toy soldiers side, I did see a couple of interesting bits on the rumour mill. The plastic Heresy era stuff could be showing up with a month or so, and the Deathwatch and Genestealer Cult lists could be some sort of box set / mini campaign (which would fit together pretty well). The Deathwatch kill team will use the Sternguard box set as a base, with another sprue of Deathwatch specific heads, shoulder pads and weapons. The Sternguard box set is already great for getting conversion bits, so if that's true it would make that set even better.
