Ya know, I received the first three omnibus paperbacks of Dark Horse's run of the character for Christmas and was very excited for Vol. 4 to come out later this year.
But vol. 4 has apparently been cancelled very recently, no doubt due to this announcement. So Marvel will probably publish their own versions of the collections now, so that's more than a little annoying.
On the one hand, I found all of the post-Busiek/Nord/Truman/Giorello comics to be very underwhelming. This was the stuff by Brian Wood, Fred Van Lente and Cullen Bunn. The writing seemed to vary between generic superhero comic writing to hokey pastiche. None of those writers seemed to have a solid grasp on the character, and the art was largely awful. So Marvel being able to imbue some new (and better) talent on the title can be cool. Plus, some solid reprints that treat the original Roy Thomas/Barry Windsor-Smith stuff with more respect than how Dark Horse treated it would be very welcome.
On the other hand, I feel bad for Dark Horse because much like with Star Wars, the Conan books were a staple of the publisher. Hopefully they don't lose the rights to the other Robert E. Howard characters and can do some cool stuff with the likes of Solomon Kane and Bran Mak Morn.
