Why do you think we will see a full art Mew V in Darkness Ablaze before Japan?
All V Starter Deck cards (Celebi V, Victini V etc…) that were released before, have no Full Art cards in English. Sword & Shield Base Set contained V Starter Deck Cards, and no Full Art cards before Japan.
Let me give you a better example:
Weavile GX, Umbreon & Darkrai / Espeon & Deoxys GX, Jirachi GX were also Starter Deck cards last year, they got their Full Art version only much later in SM12a Tag All Stars. We only have the two Tag Team GXes as Special Art promo’s so far, we still don’t have Full Art Jirachi GX and Weavile GX and we are still missing alot of SM12a Full Art cards.
Expect these kind of Japanese Starter Deck / Promo cards to get Full Art treatment in special concept pack sets like October reprint slot sets (1 gx card per pack guaranteed) similar to GX Ultra Shiny, SM4+ GX Battle Boost, SM12a Tag All Stars. The set for this year, could be the set after S4 Ashtonihsing Volt Tackle, S4a, the October slot.
tl;dr: There is little chance they will throw in a Full Art card in our sets, that hasn’t been released yet in Japan. And if it releases in Japan afterwards, high chance it will come as a promo card afterwards in English.
I am curious what they will do in our upcoming September Mini Set Sword & Shield 3.5. Little information is known about this set, but so far the release date doesn’t line up very good with the Japanese sets. It would have made more sense if it would release in October. If you want more information on why that set doesn’t line up, please let me know. Because I have lots to say about that aswell. I hope it all makes sense to you now.
