It's been a while since SW.com announced that a brand-new, next-gen SW videogame was planned for 2007. While Hyperspace members got to see some cool concept art and a short trailer of what in-game physics would be like, not much else had been revealed by LucasArts. According to a thread on TF.net, the March issue of Game Informer features a cover story on what this game will actually be about. It will center around Darth Vader's secret apprentice, and provide lots of development and insight into Vader's character in the aftermath of ROTS. You can read more in the thread here:

Rebelscum.com also has pictures of Hasboro's figures being produced for the game:

This game is going to be amazing. I went to SDCC this past summer, and was fortunate enough to see LucasArt's panel on the new technology that the next-gen game systems employ. While this video is from a different event, it's basically the same as what we saw:
