There are several big Star Wars games rumored to be in production including Knights of the Old Republic III and Battlefront III so it'll be interesting to see if the announcement is for one of those or another game (who knows maybe a new Rogue Squadron).

"I also want to give you faithful blog readers a little tidbit about our next show on April 11: It's all about STAR WARS! Last week I went up to LucasArts for an exclusive behind the scenes look at the new game THE FORCE UNLEASHED. We'll be blowing it out on GTTV with a ton of exclusive footage and some very special announcements. Spike is airing all six Star Wars movies in April and throughout the month I'll also be appearing between the movies on Spike to reveal more of THE FORCE UNLEASHED. You'll want to tune in on Sunday April 6 between the movies for a big Star Wars videogame announcement and some very exclusive footage."

I hope it's a Wii game with 1:1 controls.

@makingmusic, then I would have to go a Wii!

We know BF III is coming, it's just a question of when, and I really hope it is what Lucasarts and Free Radical were collaberating on, if so, it is going to be amazing, I can't wait, then again, I would like any star wars game!

Yeah my money is on Battlefront III for PS3, PS2, PSP, 360, Wii, DS, PC, and possibly even mobile.

plz make it Battlefront III - I have been waiting forever for this

love star wars.. love games.. will be watching on the said date

 It won't be on mobile... but it will be on the rest of them (mabye not PS2?) anyway, BF III should be much better than the originals, as I will be able to play it online, though it was an excellent offline game. I just hope they do a proper story mode

KOTOR III all the way. Loved the first one and the second was ok.

Bump. Just a reminder of the announcement tonight.

What time and timezone?
