Greater Noida West prices: Am I too late?

Since January I've been shortlisting flats in Greater Noida West, and honestly, the price tags are making me uncomfortable. I work in real estate, so I know the games. Everyone glorifies Jewar Airport's impact, but builders like Godrej and ATS are already quoting insane numbers for 3BHKs. ₹90L-₹1.2Cr for a 3BHK? Is this current valuation sustainable, ya sab hype hai? What's the *real* appreciation potential in 3-5 years at these prices? I feel like we're already at a peak. Change my mind.
