I was browsing my local geek store, a.k.a. the comic store, this evening and decided to see if they had the latest issue of Dungeons & Dragons. They didn't have number three, but they had an issue #0 Cover A, #0 Cover B, #1 Cover B,and #2 Cover B. Looking inside the cover at home (yes, I bought them all), it appears that they have about 5 different covers for each issue.
I haven't yet read the comics, so I can't tell you whether they are any good, but I'll post a comment to this post after I've read them with my take on them.
Of note, the back of issue #0 (both covers) has two scimitars and the following:
SALVATORE
DRIZZT
2011
If that's a comic book, I've got to get my hands on it.
