There is a simple fact about
RCM:
The Mint never disclose future releases. This is the base rule.
To be more detailed:
If we speak about Bullion coins (like Panda privy SML) - no one knows what and when will be issued, the info could be received only via different other sources, but not
RCM.
RCM doesn't distribute bullion coins to General public.
If we speak about Numismatic releases (NCLT), knowledgeable people can see the images and details again via 3-rd party sources 2-3 weeks prior release. In addition, Master Club
RCM members also get early notice (i think 2 weeks prior release), and all other just receive the eMail from
RCM on the release day in style "Our new coins have arrived".
