I'm with PKitty. I'd rather them get one thing right than seven things wrong. I'd rather have the 4e Bard than the 3e Bard, even if I don't have any particular personal use for the bard.
Those who want to play D&D online, get thee to
MapTool, and
Ventrilo.
I'm actually looking for another player or two for my MT 4e campaign next Saturday afternoon. It's not the same as in-person (in fact, quite a bit wonkier in some ways), but it's not bad at scratching that itch.
Heck, MapTool will probably continue to be my table of choice after the VTT, because it's friggin' FREE, whereas the VTT requires the DDI rigamarole in some capacity.
I'm looking forward to the VTT, but having some campaign tools will probably be more useful for more people anyway, so it's a good idea to focus energies on that (and a great idea to get a survey to find out what the fans want).
Use, abuse, and love MapTool. It is a lovely thing.
