The video is about 4 minutes long. While it's a good interview, he doesn't get into specifics, but does say that the Man of Steel suit has indeed been tweaked and he's been working on the suits and the project since May of last year, he said he thinks it's an improvement over the last suit (not that it was "bad") and that he will be in Detroit for the shoot starting next month until December. ...and to expect WB to release the pictures of Batman and Wonder Woman along with Henry Cavill in the new Superman suit before the movie is released (well duh), but if you watch his mouth he almost says "before shooting" but very professionally catches himself and says something safe and obvious that we all know which is that they will be released before the film.
EDIT: My dumbass does know how to post a video now, thanks to Luminus. Thank you, Luminus!
