Sector 155 Noida: Investment goldmine or fool's paradise?

Spent last week scouting Sector 155. I work in real estate but buying for myself is different, right? Everyone's hyping the industrial cluster, saying ROI will be insane in 3-5 years. Honestly not sure if it's worth the premium they're asking. The metro connectivity is decent, I'll give them that. Direct line, but peak hours are jam-packed, matlab forget getting a seat. My main worry is resale. If I need to sell in a hurry, will I actually find buyers willing to pay top dollar? It's still developing, after all. And what about the water situation? Heard whispers about tanker dependency. Change my mind.
