I think the biggest issue regarding that is Blizzards marketing itself. They done the Remaster etc, but all the events they sponsored were casual events. While this is not a negative aspect on its own, but it lets you question if Blizzard has any faith in SC:R as a eSport product on their own. When a company has no trust in its own product why should a third-party tourney organizer chip in? And its not like there are no opportunities. In Europe we have TakeTV and Dreamhack if you want to cooperate with established companies. We also don't need a huge prizepool with 6 digit figures.
Additionally there is Blizzard tournament fees and/or other conditions that are holding everyone back. Also I have a very mixed impression from Blizzard itself. It feels like some people are very passionate about Remaster and some people have nearly no connection to it and see it as another product in the portfolio.
/e: Show was great, really appreciate it guys.
