I believe theres a very good possibility The Hulk will not only talk in this upcoming revamped Hulk movie, but also that he will probably have more lines than what we saw in Ang Lee's version as well. If the style of this film is going to be decidedly less serious, less dark, and a bit more light in tone, with several more action sequences, yes. I can see the people involved giving The Hulk more one liners than in Ang Lee's version. Especially since it's been repeated that this new film is being made to reflect the comics more than what we saw with Ang Lee's interpretation of the character.
