I'm still dubious about whether it is actually F2 or not, unfortunately you can't tell from the pictures what aperture it is although the rest of the rumours were correct so perhaps that is too. Noticeably though the lens doesn't look that big, the 15-30mm F1.8 Sigma is a bit of a monster and bigger than the 24-70mm F2.8 so I can't see how a full frame F2 lens could be that small.
I do agree about 24mm vs 28mm although I guess if it can offer F2 in that small a package, that would be a reasonable trade off.
