Question regarding Summer Playoffs location

As we know, the Summer Playoffs aren't going to be at PAX Prime this year. Today, Wizards of the Coast posted an article that mentioned that they're holding the 2015 MTG World Championship at PAX Prime this year. http://magic.wizards.com/en/events/coverage/ptfrf/2015-world-magic-cup-and-world-championship-updates-2015-02-07

Did the fact that WotC is holding their World Championship at Prime play any role in Riot moving the summer playoffs away from Prime this year?
