Beyond the Jewar Hype: Real Greater Noida Market Signals

Honestly, I'm confused about market timing in Greater Noida. Everyone talks about Jewar Airport, but are current prices in Sector 150 or Noida Extension already reflecting that? For a 2BHK around ₹80L, I'm worried about buying at a peak. What concrete indicators, beyond the current hype, should I really be watching for future appreciation?
