Well, not exactly. Lego Star Wars III has just been announced by LucasArts, and a good educated guess could probably discern what it's covering...
The Clone Wars. Since all the characters in the (now getting pretty good actually) TV cartoon series already look like they're made of Lego this shouldn't be a problem, although whether the game will follow any particular episodes or doing their own a la Lego Batman is anyone's guess. The press release reads:
"LEGO Star Wars III: The Clone Wars will combine the best elements of all previous LEGO games while adding brand new gameplay to make it the most action-packed LEGO videogame to date. Developed by the same team at Traveller’s Tales that created the critically acclaimed LEGO Star Wars and LEGO Indiana Jones series, the game will ship on the Wii, Nintendo DS, PS3, PSP , Xbox 360, and Windows in the Autumn of 2010.This'll be Traveller's Tales' sixth collaboration with LucasArts, and the second since Warner Bros bought them (not sure how that works, but someone's obviously flexible). Let's hope it's better than all the other Clone Wars games, which were so bad even I didn't buy them.
“LucasArts is an amazing partner, and working with them on the next iteration of the LEGO Star Wars series continues to be a great experience,” said Tom Stone, director at TT Games. “The team at TT is working hard at making this simply the best LEGO game ever with all new gameplay and features never before seen in a LEGO game.”
