In the beginning, LucasArts mentioned of a new Indiana Jones game, not the Lego branded ones, that was suppose to come to the 360 and PS3. However, the Staff of Kings made it way to the Wii, PS2, and PSP. What happened to the version for the 360? Sure the Lego Indy games are sute and fun, but I miss the actual adventure like Emperor's Tomb.
Last I heard it wasn't "officially" cancelled. The 360/PS3 versions ran into development difficulties and the official line was something like "not currently scheduled for release." That was back in January, and I don't think anything new has popped up since. Maybe we'll see something around the Indy 5 movie release.
