What happens to your current Cisco certification expiration date come February 24?

A coworker and I are having a disagreement. Assuming someone has their CCNP prior to February 24, what happens to the expiration date? Coworker is claiming that everyone that has the current CCNP will be rolled into the new enterprise CCNP and everyone's expiration date will be pushed back 3 years which makes no sense to me. I am arguing that while you will get the new CCNP, the expiration date of the new CCNP will be the same as your current CCNP.

Does anyone have anything in writing from Cisco as to what their policy is? I can't find anything written in stone from Cisco. Thanks in advance for any help.
