Buzz Lightyear has been moved to Paradise Pier in Disney California Adventure across from Toy Story Midway Mania, along with Woody and Jessie. He is no longer found in Tomorrowland. This is what I heard anyways.
Download the Disney Parks app. (was only Android, but now available for iPhone).
(once in the park) it will tell you where the characters are.
There's even a function that will remind you that the event you would like to see is about to start.
