Great idea.
+1 with a stipulation
The stipulation would be they introduce a brand new course that doesn't become available until 1-2 weeks before the tourney. No point playing a tournament on courses the top players have played 1,000,000s of times and have every putt memorized (most times before they even address the ball).
So yes,I'm 100% for a live event. I watch tons of SC2 online and I truly love seeing the top guys showcase their skill.
