Is pre-launch worth it for Bengaluru investors?

Kundalahalli keeps coming up every time I shortlist something for investment. I'm based in Dubai, so can't do site inspections myself. I'm trying to figure out if pre-launch pricing is actually a discount. For builders like Inner Urban Infraestate, is it worth the risk buying pre-launch for better ROI, or does the open market offer similar deals later? Also, I hear about spot discounts. Are these genuine price drops for investors, or just a sales tactic to push bookings? How much can you really negotiate off the base price in Bengaluru?
