3D is the way of the future. Its expandability will cause it to win out over 2D eventually.
The 2D client may be nice, but it is not flexible. It is very rare that they can add new items, because of the amount of work, and tremendous file sizes involved in downloads.
With UO3D, it is simplistic to the extreme. The files can be downloaded quickly even by those of us who cannot get broadband access.
And speaking of that, I'd like to refute that "elitist" .
You claim UO3D is elitist, but adding to the 2D client extensively would be as well. The downloads would be so large that players like me, who are stuck on 56k modems would be screwed, to put it bluntly.
But in any event, they will move forward with 3D, because it is expandable and flexible, unlike the 2D client. That is what is important.
