Here's what I found that Dom said on the Megacon facebook page:
"We have 190 Days. No Call for games has been made, but we know Pathfinder and Legends of the Shining Jewel is on the schedule. I know some OSRIC and Savageworlds is planned. I have talked with several stores to offer MTG, YUGIOH, Heroclix and other head to head games. We have some great plans and I relish the challenge in carrying them out.
I am hoping the fans respond by pitching in and making gaming at Megacon a destination in the con circuit!"
Personally, I'd rather play some Shadowrun, Dresden or Fiasco....
