Why It Might Happen: If Avengers Assemble proved one thing (it didn't, it proved several things, but bear with us here), it was that Joss Whedon can deliver a Hulk that will make audiences whoop with giddy joy.
After suffering through early attempts to bring the character to the big screen, audiences were grateful.
Grateful enough to make a Joss-led Hulk TV show a Lost-sized hit for ABC?
Guillermo del Toro is attached to direct the pilot, and he recently discussed a mysterious writer who he was keen to involve: "I had one meeting with Marvel after Avengers and we had a very, very good chat.
"We have a writer that we want to bring on board, a very, very concrete name. I can’t reveal it, but we want to wait for that writer. It’s a writer who is otherwise engaged. So right now we are in a holding pattern until that writer becomes free. Then we’re going to do a new draft of the script."
Sounds like Joss to us.
Possible Problems: We can't actually think of any. This is looking like the most plausible option.
