Buying in Bangalore: Broker becomes buyer

Okay I'll be honest — buying for myself is a whole different ballgame than selling. I'm looking at Kannamangala, near Whitefield Hoskote Road. With the upcoming Metro extension, I'm wondering about the actual daily commute reality. Is it still a traffic nightmare or will the Metro really ease things? What's the real resident life like there? As an insider, I know what builders don't tell you. Is the investment potential truly solid for 3-5 years, or is it overhyped? Hoping for some off-the-record opinions before I make a move.
