Mind you, I liked Bounty Hunter, so wha do I know?

I don't think they'll go back to point and click adventures. Certainly not with a big licence like Indiana Jones, where you can probably shift a lot more copies on different platforms if it's a 3d action adventure.
As for re-releases, who knows. Quite a few companies are looking at re-releasing some of their back catalogue on things like Xbox 360. Konami are going to release Castlevania: Symphony of the Night (which was a PS1 game) as a download for the 360. Maybe Lucasarts will keep an eye on that. If it's popular, there's no reason why some of their old properties couldn't be made available that way.
