Wow, it looks like the studio released a bootleg of the second teaser trailer. Here's what the "uploader said on the youtube page:
I apologize for the shakiness of the video. I'm not very tall and it was hard for me to get the full trailer on screen. I noticed that there are a few scenes that are from the Superbowl Teaser Trailer, but I think most of it is new and gives out a little more information (though as to what's the plotline I still am a little uncertain. Sorry, but I won't be able to upload this in HD.
I call shenanigans. Does Paramount really need a viral strategy for this movie? It comes out June 24th. Name one more movie that you already know about that's coming out in June. See, you cant.
"I Apologize for the shakiness of the video" = "I'M MICHAEL BAY, AND THIS INTERNET VIDEO CRAP DOES NOT MEET MY STANDARD, BUT THE PEOPLE IN MARKETING ARE TELLING ME THIS IS WHAT THE KIDS LIKE.
