I'm definitely willing to collect the ongoing series, though I have a feeling the first story arc will be something of a shallow grab bag of tropes and locales to flaunt the core world. It's understandable, really, since late 2010/early 2011 is dedicated to growing the hobby, but even from a writer's standpoint it feels like a necessary part of the process.
I mean Rogers has the difficult task of conveying the essence of the game while simultaneously fleshing out his group of stereotypical icons into genuine characters. I think the series will find its footing and the characters their voices, but it'll take two or three arcs, when genuine story emerges from Fell's Five instead of the expectations of the core. Here's hoping it's still going strong then!
Then again, I don't think all the responsibility of 'getting D&D right' is on his shoulders, either, simply for the fact we're getting so many different setting series (Fallcrest, Dark Sun, Forgotten Realms, Drizzt), each with its own tone and flavor. The Fallcrest book and the Dark Sun book display vastly divergent tones which match two very different play styles. No doubt the FR and Drizzt book (are they separate?) will also have their own takes.
Fell's Five suggests a lot of Whedon-esque humor and snark, while Irvine's "Freedom" will be much more serious and grim (and the art work for it is awesome). Hopefully every fan of the game will find a book that resembles how they approach D&D.
And hey, I like the crunch promised in every issue. A Young Black Dragon given the MM3 treatment was a nice bonus.
