True, but, I think Keefe the Thief has the right of it. People are going to expect voice chat built right in. It's not that difficult to have, particularly if you build it in from the beginning. Sure, you might not get Skype level quality, but, then again, I think people will be fairly happy with reasonable clarity.
One thing I really do hope they do is allow you to synch sound files across multiple users. I know OpenRPG allows you to do this. Makes it great for having soundtracks and sound effects to go with the game. Hey, we're already online, might as well use the resources that are available.
For myself, being able to drop in my own maps is an absolute must. If we're limited to WOTC maps, I won't go for it, regardless of how integrated other elements are.
I am glad they backed off the 3d thing actually. That would make the tool useless for most DM's since it would force you to use prefab map pieces. No thanks. Too fiddly.
