Greater Noida upgrade: Is current market premium justified?

Since January I've been shortlisting flats. Currently in a 2BHK in Sector 83, thinking of upgrading to a 3BHK or villa. Prices yaar, they've shot up crazy. Jewar airport impact se sab bol rahe market peak kar raha hai. Already home loan hai. Is it still a good time to buy bigger, ya wait karna chahiye? Is this price jump really justified?
