Is the old traditional front push EF/MF style dead?

Hey my EF/MF family:
I have been thinking on the constant evolution of our hobby, on the old Miggle board we use to have great discussions on how evoloution of EF/MF may squash out more traditional forms of the game, i have realized through me working with the kids that starting simple was best, i want to implement a 4.0 style when the kids get a strong grasp of the game, what do u guys think, have we moved past the EF/MF days of traditional EF/MF style play?
