Greater Noida: Is IT/SEZ the true demand driver?

Okay, I'm just fed up of renting. Landlord raised rent again, so I'm finally taking the plunge in Greater Noida. Everyone talks about Jewar Airport driving prices, but I honestly think IT park and SEZ developments are the *real* game changer for end-user demand. Is it just builder marketing or are they actually bringing jobs and people to areas like Noida Extension? Change my mind.
