The V site has updated with this fantastic news.

Yes, it is true. The Vendetta trailer debuted at Comic Con and now, those who were not there will see it online shortly. In fact, tomorrow. In High Definition and with 5.1 surround sound at its largest size. Damn I love the march of technology. While the Matrix trailers we encoded in 2003 looked great, we could not encode true HD. Now we can. And it looks spectacular!

Wooohooo!

UPDATE

CHUD have posted another con interview although I think its a rehash.
