Star Wars: Clone Wars (http://www.comingsoon.net/films.php?id=41868)
Teaser (http://starwars.com/video/view/478.html)
naturally I want to see all the comic book movies coming out, but in addition to your list, I also want to see The Happening (M. Night Shyamalan) and Step Brothers (Will Ferrell).
I think last year had way more big blockbusters though. This year has a lot of big ones too, but in 2007 I was at the movies nearly every weekend it seemed.
Kung Fu Panda and Love Guru are the only movies that I'm not going to want to see in theaters. I may not get to see all of these, but I want to. Also My Name is Bruce looks to be really awesome, just because it has one of the awesomest plots ever.
Also releasing this summer:
Babylon A.D. (Vin Diesel, Sci-Fi)
Tropic Thunder (Stiller, Black, Downey Jr., Comedy)
Bangkok Dangerous (Nick Cage, Action Thriller)
Meet Dave (Eddie Murphy, Comedy)
Since Lost Boys 2 is a straight to DVD, I think it shouldn't count.
