Yes, totally psyched. However, I have one bugaboo: if this is taking place 30 years after Return Of The Jedi, that means that, according to the Expanded Universe, Chewbacca has been dead for 9 years, since the character was killed off in the book Vector Prime, during the Yuuzhan Vong war, which takes place 25 years after the Battle Of Yavin (ABY), which is how the timeline for the Star Wars Universe is put together.
Interestingly, the movie picks a time, which would be 34 years ABY, where there is nothing written or done within the Expanded Universe.
