I jetted out to the Battle Bunker on my lunch hour today and sure enough - Rynn's World was in stock, so naturally I picked it up as well as the new Tyranid Codex. I have not intentions of starting a Tyranid army (yes, you heard right), but I still wanted the codex. Thumbed through that really quick and the new art is awesome. I'll read through it as soon as I get about a hundred pages of Rynn's World under my belt.
I like the format of the new Space Marines Battle series. It's a larger book and contains battle maps of the campaign. Two others are due out: Helsreach (Black Templars) and The Hunt for Voldorius (Raven Guard).
Okay, off to read Rynn's World. Thanks for the heads up, fellow gamers.
