Like, thinking about it, there's a different fighting game for everyone this gen.
Want a classic? KOF and SF.
Want 3D fighter? Tekken.
Want a character creator? Soulcalibur.
Want cheesecake? DoA.
Want an anime fighter? Cross and DBFZ.
Want some blood and a samurai era setting? SamSho.
Want loads of gore? Mortal Kombat.
Want something inoffensive and super fun for literally everyone? There's Smash.
There's even DISSIDIA and MvC again, even if they're of... 'eh' quality.
And all of these games (except for MvC) are still getting both free updates and character DLC.
Point is, I'm not sure what they could announce at E3 that isn't better suited for EVO or just announcing on the publisher/devs' terms, given it's probably niche at that point.
