I've seen videos of people using all of them, the mega stones being obtained through hax

So I'm wondering, will we ever get the rest of the megas in sun and moon?

I really like the megas, training and breeding mega pokemon is one of my favourite things to do, but I'm sad to see that a ton of megas haven't made it to sun and moon.

Does anyone know what the future of megas in sun and moon is?
