Green, Ruby, Black, Rose, Blue I think whoever reserved a Monaco Card wants to try the App and receive the card asap. Colors and tiers may change but I focus on the working product. 
Yea pretty card is important but a working product is more important! I thought they had already produced thousands of cards, so not sure what impact changing their cards will have on delivery (if that is the case).
What's happening? Are they going for a redesign that comes with further delays or what is the issue?
