Experion 151 Noida: Pre-launch pricing ka kya scene hai?

Found an interesting video on Experion Sector 151 Noida. Honestly, the 3 & 4 BHKs look super premium, especially that separate 4 BHK tower with its own lobby. It's pre-launch abhi, aur they're hinting at ₹3.6 Cr+ starting. Noida mein itna high price point... I'm really considering it for a potential buy. What do you guys think about Experion as a builder, or Sector 151 ka future for long-term growth? Any real experiences, good or bad?
