We have unofficial confirmation of Man of Steel footage debuting at the MTV Movie Awards as it's said that Henry Cavill will be presenting a teaser.
The 2013 MTV Movie Awards listing at Wiki has - or had - Henry Cavill listed to be presenting a Man of Steel Teaser.
We do know that Henry Cavill will be there as a presenter as the official MTV Movie Awards website lists the new Superman.
However, we weren't sure if they were debuting any new Man of Steel footage or let alone trailer #3, which is the heavy favorite being speculated amongst fans.
If Wiki is, indeed correct, MTV and Henry Cavill might be just featuring a short Man of Steel teaser with the full trailer #3 reveal possibly coming online later.
Interestingly enough, the Henry Cavill info on the Wiki Page has since been removed -- completely; meaning, Cavill isn't even listed (though it's confirmed he will be a presenter).
Obviously, Wiki could be incorrect, but it seems more than likely we'll be getting new Man of Steel footage with Henry Cavill at the MTV Movie Awards in one form or another.
There is a Man of Steel viral marketing campaign going on this weekend as well, which might be the big trailer #3 reveal.
Here's the screen shot we managed to grab at Wiki before it was taken down:
