As well as the first public showing of Indiana Jones? and the Power of Euphoria? at E3 on May 10-12 and the probable first showing of LEGO Star Wars: The Original Trilogy, it seems that an expansion pack for the latest Star Wars RTS Empire at War will be announced. There was a tipoff here on the LucasArts forums a few days ago;
We've been preparing for E3 and it's been a wild crazy ride. If anyone is going to E3 in a couple of weeks, stop by the LucasArts booth and check out the line up for this year. There are some really great games in the works including more stuff in store for Star Wars: Empire at War.Also there has been a passing mention of Vader's backstory in a recent Jim Ward interview which gaming sites everywhere have taken to mean that there is a Darth Vader game in the works. Ward has also mentioned in the past year that he would like to see Mercenaries become an ongoing franchise, so it won't be any great surprise if a Mercenaries sequel is announced.
