Calling a Swan a Duck isn't really right either. Until it actually comes out, no one knows what it will be. That's his point. Anyone can have an opinion. However, making assumptions based on something that you haven't seen, heard, or played with and calling it EITHER a Duck or a Swan is premature and pointless. Just hope for the best. $10 is not a big gamble even if it happens to suck. Take the Extra 5 levels, abilities, and corresponding points and move on.
We know exactly how big it is, they've told us - the size of Belsavis.
