According to a tweet by MLG operations manager Adam Apicella, there will be no MLG Summer Championship this year and the next grand event of such proportion will be in Dallas, November 22-24.
It's not like there will be no MLG-branded event between now and the November event. A follow-up post by MLG CEO Sundance DiGiovanni hints that there might be something non-championship in the Summer as Las Vegas, New York and Seattle are mentioned.
We are excited to announce that our next #MLG Pro Circuit Championship event will be held in Columbus, Ohio, November 22 - 24.

The Columbus announcement states the next 'championship' event will be held there...still room for a few surprises. Vegas?NYC?Seattle?
