Variety.com just posted and article about the new Star Wars: Force Unleashed game for the PS3 and XBox 360. It said that both it and the New Indiana Jones games were separated into 2 different teams. The Star Wars team created 3 new software engines that are suppose to be heavy in AI and the most advance in the industry.
Apparently, the Indiana Jones game has been delayed to take advantage of this new software. The article said that the Star Wars game was the first wave and the Indy game will be version 2.0. Much akin to Empire Strike back, where the software will be amped up to the next level for Indy's game. Apparently, Lucas Film has taken notice of the market for video games and is putting a lot of emphasis on the next two titles it is about to release. I would say its a safe bet that the Indy game is hush, hush right now so they can exploit as much as they can for the new Star Wars release. Then after it explodes on the market, they can say, "Well if you liked this, how about this.? At least that's what I got from the article; notably the first video game article ever given by Variety.
