Hello,
I was wondering how many different roomkey cards the Rio had for last years 2013 WSOP? So far I have come across 2 different versions pictured below. The first scan is of the card I have, the second is from a currently running eBay auction to show the difference from my card. Thanks for your help!

PS: Does the Rio have a new room key card for this years 2014 WSOP? If so I would like to get one. A friend in Vegas told me that so far they are using the black card from 2012. I would also like a slot players card from this year, 2014. Thanks!
