Re xhonzi and Erik Pancakes...
...thanks so much for those detailed answers guys! It's this insanely complicated and convoluted publishing schedule that has always put me off getting into Marvel :-(
I like a nice self-contained linear auteur story myself (More the British comic style I guess), as such the 25 Abnett issues appeal to me (Plus I've liked a couple of Dan's 40K books). I might just dip in there and see if it grabs me. The art and script look appealing...
If I like it, I'll go back and fill in some of those gaps you both mention like Annihilation.
Thanks again :-)
