Since the PS3 seems to have become Telltale's favorite of the three consoles I'm sure it's being planned, but nothing like that has been confirmed yet.
How good is your computer? Telltale's stuff is designed for the PC, so if your computer can run it that'll be your best bet. You can download "Abe Lincoln Must Die!" for free
here, if you want to test and see if your computer can handle it.
If you don't have a good computer (or if you just really want to play it on a console), the first two Sam and Max seasons have also had disc releases for the Wii. I'll warn you, though, they're not very good ports. I mean, the porting job isn't bad to the point of being unplayable, but I'd only go with the Wii version if it's your only option.
Oh, and if you really want to try out more Telltale stuff on your PS3, there's also Strong Bad's Cool Game for Attractive People.
