Excellent look and feel to it all, really gives you the impression the terrain is stretching out for miles. A few little things like floaty physics (maybe on purpose?) and satellite view distance (fixed in later patches?) don't detract from the overall "Epic" feel.
One question I always wanted to ask... and I might know the answer already... it seems like the alternative to enlarged terrain is miniature units... why not just drop the overall size of all objects by 2/3? I know that, from my own experience, they seem very small already (as seen in Max) and there are particle distance issues and all, so maybe that's why...
So, in all, awesome job. I've always wanted flight sim view distances in a game like BZ, and now we have it!
