I'm about a week away from starting up my
Pathfinder Rise of the Runelords campaign, so that will be a Third Edition game.
It will also be my last Third Edition game unless I turn out to hate Fourth Edition, since if I have the time and energy to start another game before June it certainly wouldn't be a
Dungeons & Dragons game. I am far more likely to run a one- or two-player
Vampire: The Requiem or
Mage: The Awakening game, or
Star Wars Saga Edition set in the Knights of the Old Republic era, or
GURPS in an alternate history setting, or . . .
You get my point. I'm excited about Fourth Edition, but
D&D is hardly the only game I care about.

Wizards of the Coast should be thankful I don't know enough about
Hunter: The Vigil to start getting excited about it!
