Upgrading from 2BHK in Delta 1: What's next?

My 2BHK in Delta 1 ab chhota lagne laga hai. Soch raha hoon upgrade karoon 3BHK ya villa mein. Dekh raha hoon ATS ya Godrej ke projects Noida Extension mein. Kya 3BHK ka price jump worth it hai for future appreciation, ya Yamuna Expressway pe villa lena better hai? Already home loan chal raha hai, budget ₹1.5 Cr tak hai.
