News- Jeph Loeb and Ed McGuinness on unnamed Hulk project

Newsarama has a piece today about Jeph Loeb and Ed McGuinness collaborations. The article focuses on their upcoming work on Ultimates 3 and Ultimates 4, but Loeb briefly mentioned working on an unnamed Hulk project:

Finally, in regards to future collaborations between Loeb and McGuinness, Loeb told Newsarama, "Ultimates 4 is up first. Hulk follows," adding with no pun intended, "That's much more gray then the Ultimates stuff, which we are starting on now."

Maybe I didn't read the article closely, but that "gray" comment has me scratching my head (besides the obvious pun, which is apparently unintended).

Here's hoping that whatever comes of this project, it won't be in Hulk's main title. Hulk: Gray was a stunning disappointment, speaking both as a Hulk fan and someone who was impressed by Batman: The Long Halloween and Superman For All Seasons.

I guess odds are that whatever he's doing won't be in Incredible Hulk, simply because it seems doubtful Marvel would want to name the post-Planet-Hulk creative team this early.
