Site visited Godrej project, Sector 150 — pre-launch offer game?

Visited a Godrej project in Sector 150 last weekend. Builders always push pre-launch offers, calling them 'early bird discounts'. I'm in real estate, but I question this. Is the discount real ya bas inflated pricing ka tactic? Always compare per sqft with nearby ready projects. What's your take on actual pre-launch ROI in Noida?
