Honestly, that's an outcome I'd be happy to see. If this tournament pushes people into unexpected counterpicks and new tech, that would be a win in my book.
As I was computing the historical matchup chart to put into the tournament intro post, I actually ran the numbers to see how confident we can be in particular matchups in that historical chart. In this chart, the number in each box is the 95%ile confidence interval for the historical matchup number (I'm not a good enough statistician to correctly define with the confidence interval is, but roughly, if the confidence interval is small, that means we can be more sure that the matchup number is accurate).
As you can see, there's actually a pretty wide margin on most of these matchups, because of the small sample size, but in particular, BBB/Ven, BBB/Menelker, BBB/Jaina, BBB/Gloria and Gloria/Ven are especially uncertain. (Looking at @mysticjuicer's records, they've all only been played about 30-40 times).
