It looks like not all regions have been updates to the new website. Either that, or just inconsistency. Yesterday I booked a hotel in France. New room selection concentina and the ability to add a credit card to my account.
Today I booked a hotel in India. Old format and a message saying that although I had a credit card on file, that function is not working yet.
It certainly looks like a bit of a mess, IT-wise.
