Trailer to what was leaked by the ESRB a few weeks ago. I have never played a Sam and Max game, so I am looking forward to the release 
Here is some info about the game.
The cost
Five mystery-packed games for $34.95 – that’s less than $7.00 per game! If you preorder the game starting March 18th, you can get the season pass for $29.99
Differences between versions?
The games are virtually identical across platforms, with the exception of appropriate tuning for the platform (the game interface and controls, for example.)
Release date for Episode 1:
April 15th 2010
Screens and more info can be viewed here: Tell Tall Games website
F5ing the PSN Store like a madman.

Awesome. Telltale’s been putting out a slew of great games, hopefully they’ll backport a bunch to PSN also; at least the first two Sam & Max seasons would be nice.
That’s awesome, Sam and MAx Hit the Road was one of my favorite games as a kid!
