wesker and phoenix wont do it. wesker is too basic, have too many bad match-ups and people got him figured out now, while phoenix is too risky due to meter nerf and many other counters to her even if she turns dark.
japanese players wont do it neither. i saw them getting absolutely mauled by yipes and champ in fgtv, they are going to struggle bad against players of similar quality. and there is more than 8 players in usa on that level. they can destroy most second top tier players though. their best player is probably abegen (tron, thor, she-hulk), but he is in the hardest pool. surprisingly umvc3 have very consistent results even though it is a extremely random game.
i think zak bennett from uk has a better chance of top 8. my prediction is there will be a wesker in top 8 but he will get exposed and lose bad. there will not be a phoenix other than champ in top 8. chris g will make top 8 and both he and the steam monsters will be salty about it. a zero player will dominate his way to top 8 and lose because he dropped a combo and get xfactored. there will be more than a few magneto and doom in top 8. wolverine will be in top 8 and fools on srk dreamland will still think he is not top tier. if an iron man player plays on steam, he will get bodied and idiots will still think the character is underrated. a vergil will win evo.
i dont think eita will do that well. he is good but not on the level of tokido, daigo, mago, etc. aka the gods level.
