Interestingly enough, the
AmiAmi sales page for Bandit Ring has been updated with some numbers for card types. They claim that there will be 81 cards + URs, with 11 of those being RR (the Japanese rarity for EXes and M EXes) and 11 as SRs (FAs). However, if you add up all of their given numbers (37 C, 24 U, 9 R, 11 RR, 11 SR), you actually get 92 cards (without counting URs) rather than 81, so I dunno. >.>Maybe that 81 number also doesn't count SRs?
In any event, 11 SRs is the same number we got in XY6 (Emerald Break). There were only 9 RRs in XY6, but there were also the Rayquazas released in the Mega Battle Deck which would have brought the full number to 11.
I think it's unlikely that we'll get any set EXes/M-EXes without corresponding FAs, so I'm not sure how the balance would be restored. Maybe just an extra EX/FA combo that isn't a Mega. If that's the case, we may be looking at 3 EX/M-EX combos and 4 non-Mega EXes. However, there's also Hoopa and Hoopa Unbound to account for, and it's likely that those cards as well will be RR or an RR/SR combo.
In any event, I have my fingers crossed that we'll start getting leaks soon. I'm impatient.
EDIT:
I will be so mad if there's no Unown in this set. :/
You can can come join my club of "please make these Pokémon in the TCG again, pretty please, with sugar on top" if you like. I'm gunning for Shellos/Gastrodon, myself.
