Dwarka Expressway completion ka real impact kya hoga?

Kya Dwarka Expressway completion se prices aur upar jayenge? I'm so fed up of renting in Gurgaon, finally planning to buy. My budget is around ₹1.8 Cr for a 2BHK. Thinking of areas near Dwarka Expressway like Sector 102 ya 109. People say prices wahan jump karenge after completion. Is it true? Or is most appreciation already factored in? Should I wait for Global City announcements or buy now before prices shoot up even more? Honestly not sure.
