You and everybody else wants this game to be 2D title because there hasn't been a brand new - like built from ground up new - 2D fighter from Capcom in a w-h-i-l-e. And, most probably, it will be 2D title. Then I want this game to be 3D title because there hasn't been a brand new 3D fighter from Capcom in like ever and I think it would be a much needed step forward. And then there's probably someone whom wants this to be ASCII title because that would be totally old school.

and people want this to be 2d because 2d games play entirely different from 3d games.
So it's not like 3d is a progressive step from 2d, as they have entirely different game play mechanics.
