Urbtech India KP2 mein pre-launch pricing ka kya scene hai?

Visited Urbtech India's site in Knowledge Park 2 last Saturday. Honestly, as someone jo real estate mein hoon, I'm finding pre-launch offers to be pure marketing. They promise early-bird discounts but final price mein koi khaas farak nahi dikhta. Matlab, is pre-launch pricing just a gimmick for builders? Kya lagta hai, should I wait for ready projects or try to negotiate on these "early-bird" deals?
