Sector 9 Noida property prices are already maxed out

Are Sector 9 prices justified anymore? I'm seeing 3BHK flats quoted near 2Cr, but honestly not sure it's worth it. The metro is great, sure, but what about water supply? I've heard mixed things. Anyone living there now experiencing regular water issues? Also, resale – can you actually get a good price if you need to sell quickly? What's the real appreciation potential looking like in the next 3 years? I've seen this happen before. Any thoughts?
