tickets for worlds @riot

hello, i was wondering if its possible to just get a date for when tickets will be available to purchase. i saw a post where it said mid July, but based on the size of the Chicago venue there really wont be many tickets vs amount of people who will want to go. this would be my first chance to attend a big league event and i really want to make sure i get tickets, but im afraid that tickets will go on sale and be sold out before i even get a chance to check. i would really like to know at least a little more info so im not just refreshing the page for the next 2 weeks. thanks
