I would feel pretty confident saying right now that KDZ, Denzell, Rico, DarthArma, King and a few other guys have rightfully earned their spots as "top players". There are plenty of unknowns, but there are also people who've proven themselves to be in that "top tier" already -- and there's not much that can take that away from them.
And really when you look back at MK9, there were just as many guys that had off nights or would be upset. Dizzy, MIT, DetroitBallin, Curbolicious, m2dave, Tyrant, PL, ForeverKing, Wafflez, Crazy Dominican, Riu48 all had their big triumphs, and also tournaments where they didn't make as much noise as expected, didn't make it out of pools, or didn't make Top 8. While there were some extremely consistent placers for streaks like Pig, Bit, Maxter and REO, there was also a lot of fluctuation going on throughout the game's life.
