>>29435471>Mega Stone and Z-RingXY had a Mega Ring toy that had Ash and Serena's voice shouting for Pokemon to mega evolve, but neither of them had a ring.
The Z-Ring is similar, they'll advertise it hard at the start of the series because it can be used in the SM games but as time progresses there will be other things to market. Instead of a Mega Ash got AshGreninja which they marketed hard since it's debut. And while Ash may and will likely not get a Mega in SM it allows him to carry over the bracelet for future generations where he may get one. But by Gen 8 they'll likely have a new device to give him and market.
Actually, for whatever remake that happens in Gen 7 we'll likely get a new and improved Z-Ring similar to how in ORAS we got Mega Bangles instead of Rings.
So Ash may be getting an upgrade at some point. That being said the Z-Ring opens doors for the future of Ashs character, whether he acquires a Mega now or long into the future.
As for his him learning Z-moves without the bracelet, who knows. We got chuuni poses with AshGreninja when he goes Synchro and it's popular, they could easily continue the trend by having Ash pose to activate a Z-Move without the ring.
>Legends and MovieWe know about Topo Koko, literally every other legend is on the table for a future movie deal because of this.
What we'll likely get is:
Lunalaa/Solgaleo movie
Marshadow movie
Possible Zygarde, Ultra Beast or Gen 8 mythical movie
