All in all i think it's a decent move by HDFC,
Look what ICICI have done recently, reduced eligibility criteria, removed spa benefits, introduced new cards(Emerald Private Metal),
I wouldn't be surprised if they add spend criteria on Emerald PVC considering how many have gotten this card LTF
Even IDFC devalued its wealth card,
Axis just ran it's cards into the ground, over issuing and plathora was amongst the reasons
Even Amex had to reevaluate Plat Charge recently, and by the looks of crowding at centurion one can ponder on why
Atleast HDFC is retaining its value by making it more exclusive, not bad
