There's plenty to come on season four of True Blood.

But creator Alan Ball took a few minutes at the Television Critics Association’s summer press tour last night to offer up some season five scoop. For starters: there will definitely be one.

“Everything ends, and there will be an end for me on this show at some point,” Ball said, confirming he's signed a new deal with HBO. “But I don’t have any desire to leave because I’m having more fun than I have in my entire life.”

Ball also said the writing team has already starting plotting for next summer and teased that it will “explore how one of the vampires was made,” while also introducing new characters.

The producer didn't say into which vampire's past we'll delve, but it's safe to assume Pam, don't you think?
