Central Delhi 3BHK: Has appreciation peaked?

Honestly not sure if I'm overthinking this, even though I work in real estate. Looking at a 3BHK in Central Delhi, Kholi Group perhaps. With UER-II and Metro Phase IV, are areas like Vasant Kunj still good long-term bets? Has appreciation potential peaked, or is 1.5-2Cr for a 3BHK worth it for future ROI?
