We had a discussion about this before.
the concept of the Voodoo Zombie is still around.
Given that Romero's major influences, I am Legend and the like are still around, someone may be inspired to do something like that later.
I had also proposed that it would lead to a wider variety of undead in cinema, since the classic zombie is now a reanimated servant obedient to it's master's whims.
The ghoul might become the counterpart to our classic zombie.
