Ultimately it'll be up to yourself, uber and siradam...but I'm sure either of them would handle league business admirably in your absence as they've done before. You could always play your game on the 5th or 6th, upon your return.
No doubt they're more than capable, but the plan all along has been to wait about two weeks (which is what we've done in the past based on when the roster comes out) before we start. That's part of the reason I scheduled the vacation when I did. I know everyone is rearing to go (so am I) but we're going to be playing this game for the better part of the next year, waiting a few extra days isn't going to kill us.
There's been some talk of a kickoff tournament after the game comes out to help get people in the swing of things while we wait for the roster update. Hopefully that will hold people over.
