That was touched upon in the article.
MK in 3D isn't the same on one respect because they eliminated the aerial combat almost completely.
They are bringing that back and its going to not suck.
I agree though MK in 2D was amazing.
MK in 3D for me was cool but it definately lost alot of charm.
Hopefully they won't lose all the MK charm by killing off all the current story and characters and starting anew....
