You can notice new things like a short Vergil vs Dante footage and a new scene from what i think is Vergil's opening.
Vergil's opening really resembles his opening from DMC3SE, only much more elaborate and badass.
A bit of an embarrassing preview, though. They claim DMC4PC came out "a couple of years ago", they corrected themselves wrongly by saying there were 6, not 5 playable characters (unless there is something else that's hidden or they were talking about Corrupt Vergil), and claimed the only release date info was Summer TBC when Capcom has already revealed the exact date.
