We already knew that there was going to be a Shroud of the Avatar demo held through/via Rooster Teeth next month, and it would seem that this is when that will take place:

Richard Garriott
July 6th, 4:30 PM to 5:30 PM in Room 19 at RTX 2013

Richard Garriott, video game developer and entrepreneur is at RTX for the first time. Join him as he discusses his experiences and his new game, Shroud of the Avatar!

RTX takes place at the Austin Convention Center in (where else?) Austin, Texas, from July 5th to 7th. It also appears to be entirely sold out, so hopefully you got your ticket(s) already if you were planning to attend it.
