Call it cope but I think Megas will get retconned to work similarly to Battle Bond Greninja and that it was a development Gen 6 was initially leading up to before being cut short. Think about it:
>A significant chunk of megas already benefit from using their first turn in base form (Moxie, Scrappy, Revenge kill, Speed boost)
>Megas have already been shown to not explicitly require an attuned Mega stone as long as they get exposed to Infinity Energy
>ORAS explains that Infinity Energy is just Pokemon life energy and that's probably given off when they faint/die.
This nigga right here was said to emit energy signals identical to Mega Evo. I think the leaked "new concept" of Megas is an extension of what they were already introducing in the tail end of Gen 6 but never got to due to the shift in gears that happened because of SM.
