Based on how the year ended, 40% Hbox, 30% Mango, 20% Leffen, 10% other.
Hbox is still the favorite going in to practically any set, even though the gap is closing.
Mango ended the year super hot, he appeared confident about 2020, so if he still has that fire he absolutely has a good chance.
Leffen was the best player against Hbox last year. If Leffen gets by Mango to play Hbox he has a solid chance.
Axe has to get by Hbox. Not likely. If he gets over that hurdle he has a decent shot against the rest of the field.
Zain has to get by Axe. Again, if he gets by that he has a decent shot against the others.
Wizzy plays Leffen. Totally doable, but Wizzy hasn't seemed as good as he was in the middle of last year.
Can't count out M2K, but he's seeded to play Mango -> Leffen -> Hbox -> rematch against one in GF. Even if he overperforms I can't imagine him winning that gauntlet and losers would be even more difficult.
IBDW has the potential to beat Hbox which would make the rest of top 8 very interesting, but I don't think he can take the tournament over the rest of the talent attending.
Even taller task for anyone seeded outside top 8.
