Good news and bad news:
The good news is that things are shaping up nicely and we're going to have a healthy turnout for this bad boy.
The bad news is related to this:
OK, I suppose I'll tease this here, though let me be clear: all of the details of this haven't been worked out and it may not happen for this tournament, but it's at least in the works.
For the elimination part of the tournament, I plan to have a "feature match" which will be live-streamed with commentary. The store has a setup where they will live-stream games from their MtG tournaments and I should be able to use this for Dominion. I will post more details when/if I have them.
It's looking like this won't be happening for this tournament. I've talked to the guy who runs this, made it clear that I'm willing to pay his fee for this, and let him know the details and my contact information. He hasn't gotten back to me after I checked up a couple of times. So there's still a chance that this could happen if he randomly shows up and just hasn't bothered to contact me, but this is looking like a no.
These people love their Magic so much, but they don't realize how awesome Dominion is. We'll get 'em someday, guys.
