Assuming everyone is still around (which I doubt, since it's been over a month), there's more than 4 people. A few people withdrew, and some people never actually had a match.
Just sayin', there's more than 2 rounds left.
For my part...I dunno, on the one hand it seems like it'd be futile to try and pull it all back together, but I came in hoping to play people, and I still want to play people, so I'm all for playing on.
