Chase is not necessarily moving away from Mastercard completely. I learned this while talking to a Chase agent regarding the Presidential Plus Card from United. I was asking them for a chip card. The gentleman said that I could hold onto the Mastercard and get a chip card around July, or I could convert to a Visa card with exactly the same benefits but just a different number and get a chip card within 5 days. I asked him three times to make sure the benefits remain the same including the elite qualifying miles and he said yes. He also said that even after I receive the Visa version the Mastercard will remain active for a short period of time, and if I am not happy with the Visa I could simply revert back to the Mastercard and keep it and return the Visa. This is important because the Presidential Plus Card is grandfathered with its extraordinary benefits, and you cannot get a new one anymore. you can have one as long as you had one while a member of Continental One Plus, and have continuously had one since then.
I just finished converting every card that I have to chip, except of course the AGR which I cannot convert.
Oh and I asked about chip and PIN and was told to expect the same chip card to be converted to chip and PIN if so desired by very late this year or early next year.
He also said that the Visa version of the Presidential Plus will work with Apple Pay. I did not ask if there was any plan for the Mastercard version to work with Apple Pay anytime soon.
