VIDEO: New 'Transformers: Revenge of the Fallen' trailer leaks early

Score another victory for cellphone cameras: Some intrepid fan managed to catch an early screening of the next "Transformers: Revenge of the Fallen" and posted it to YouTube.

Okay, so you're only getting about a day's head start -- rumor is the trailer was headed to theaters for the May 1 releases anyway -- but this one definitely moves us from "maybe" to "definitely" on whether to catch the movie soon as it opens.

Spoilers follow...

Image quality is low, but here's what we saw:

• Sam Witwicky heads to college, where he's accidentally exposed to a fragment of the first movie's Allspark;
• The feds tell Sam the symbols he's drawing match others in ruins across the globe;
• An undersea exploration vehicle revives Megatron, sent to the bottom of the ocean in the first movie;
• Sam shouts that Megatron wants the Allspark information apparently transferred to his mind; and
• Robots fight everywhere: in pyramids, forests, cities.

The robot battles, even blurred, look intense. Also intriguing is what appears to be a giant robotic vacuum cleaner toward the end, sucking up sand and other Transformers. What the heck was that? We'll find out June 24.
