I think the slow trickle of characters is better. People are feed up with the "super/arcade/ultra/super ultra editions" The slow drop of characters and updates every year (although pretty much the same thing really) is more acceptable to the masses now.Along with selling characters instead of cosmetics.
it's gonna be tenkaichi 3 all over again with the characters being clones of each other

and the trickle of characters doesn't mean anything when those characters consist of abigail and falke
