Won't happen as long as the real money auction house is around.
EDIT: why is Zerg your hardest matchup? I play Zerg.
So much versatility when played correctly. Zerg is certainly the hardest race to play but i also feel like its the hardest race to play against. You have to contain them, prevent creep expanse, defend from mutalisks, destroy overlords, and try and counter whatever they are building. As soon as you counter them, they can counter you without building any new structers (if they already have them up). When it gets to late game ultralisks **** everything.
Terran vs zerg is pretty much terran having to capitalize on zergs mistakes and if they fail to, they lose
