I definitely put alot of blame on Marvel Editorial for the Hulk ( and other Marvel Titles ) mess we have had off and on for years. I personally blame Axel Alonso more then anyone else. Alonso really messed up by saying this Generations storyline was not going to be a time travel story. But I won't say anything else about editorial right now. But to answer your question if I could pick a writer I would say Kurt Busiek. My reason for that is the outstanding job he did on Fixit when he wrote The Order. If he did become a writer for this book he would have to do The Grey or Gravage Hulk. He made Fixit so bad ass and entertaining. I would not want him writing The Savage Hulk.
Guess the other Generation stories will involve time-traveling then too?
