Every even gen 2 new eeveelutions were announced. So far it is just a coincidence. (Happened twice) And you can't count on coincidence to be pattern.
It takes three to become a pattern. If it happens now, we can fairly expect 2 new eeveelutions in gen 8.
But yeah adding dragon eeveelution would be great, and since they just made dragon cards maybe a tie in could happen there, I want a ghost though. --- SSB4 dream roster: http://imgur.com/DfdocHN.png 45/50 characters---I support for Echo type pkmon gen 7 This is my flame shield.
