I don't consider room and time the same thing. As far as space, there's plenty of space for setups if they wanted to run 7 games instead of 6. Since EVO has been growing, the amount of games should also grow at least by 1. Plus there won't be a bunch of shirt monsters to account for, so it shouldn't be a problem, especially with doing 16 man pools.
As far as time, there's time to run the actual tournament, but not the time to show top 8 for each and every game. KOF finals took almost 3 hours to complete. You can cut the finals to top 4 which I would prefer rather leave a game out.
