The speculation turned out to be correct, there is a LEGO Indiana Jones game in the works (as indeed are physical LEGO Indiana Jones sets).
Reported by theforce.net:
Probably the biggest new to come from the Lucasfilm presentation is that we can expect a Lego: Indiana Jones video game in the summer of 2008. Comic-Con fans in attendance were then treated to the first ever glimpse of the trailer for the game.
Considering the LEGO sets will be Nazi-less according to inside info, it will be interesting to see what enemies the game uses in the Raiders & Last Crusade levels. Strange it's only covering the first 3 movies, and not the new one.

Update by Jason: Just in case this is significant to anybody, the press release for the LEGO game confirms that the, erm, live action Indy game will take place "a year after The Last Crusade." You know, for any of you who were waiting to peg it in the appropriate place on the Indy timeline, or something.

*groan*
LucasArtsJim Ward wagon, is by hinting at a Full Throttle GTA-clone in his general direction. Or even a Monkey Island GTA-close... *shudders*I just wonder whether the same formula that worked with Star Wars will work with Indiana Jones. I mean, how will it be prevented from getting stale and how will they make up for the lack of characters to control?
