Platinum or Diamond Tier

I won't be getting to Vegas until Nov. If I reach Platinum or Diamond tier while I am there, is it only good until the end of the year? Thanks,

It should be good for the remainder of 2013 and for all of 2014....actually the new card for 2014 should say it expires March 2015.

Since the TR rules changed this year, I've been wondering about this very fact. Over the last 10 years or so, we have become accustomed to cards expiring in March. Has anyone seen in print that "March 2015" is the 2014 expiration date?
