I think that the game exists because all the SC2 pros decided that the game is starting to become a bit too old and blizzard cannot be trusted with making games anymore so they gotta make starcraft 3 themselves.
they dont expect to be funded only by kickstarter unless they get like ten times the goal but its more to see if people want that sort of game to possibly help securing publisher funding or just fund themselves like they have done the years until now
I was just about to comment about slice and dice too
