I don't know if this even counts as 'news', but Eurogamer are suggesting that TT Games' may be doing Lego Indiana Jones II. They suggest that it may contain levels from Kingdom of the Crystal Skull. Shocking stuff, I know.
Eurogamer then went on to suggest that Double Fine may be working with Jack Black, that Ron Gilbert may have a new game based on his character Deathspank in development, and that there is a strong possibility that the sky is blue.
jp update: Yeah, so the LEGO Rock Band game (see comments below) was confirmed, and the 'LEGO Indy II' game's existence was leaked at the same time, so...

And they can re-release FOA while they're at it.
The Lego Rock Band idea sounds like a baseless rumour (thankfully).
I'd quite like a game based on an original LEGO line, like maybe the nice new Pirates theme.

I didn't know about the Harry Potter thing, but that would explain a lot. With Warner Bros owning the studio it's surprising a lot of people that TT Games aren't doing Lego Harry Potter.

"Smith also told us of plans to release a new LEGO title in 2009. Significantly, TT Games boss Tom Stone revealed that it's not going to be Star Wars, Indy or Batman, but something completely new."
