That should be possible, but Masuda already slammed the doors that long ago before Omega Ruby and Alpha Sapphire are available, that is why there wasn't much uproar for ORAS Mega Stones in XY. {XD} Sneaky guy.
While anime's not a good source for Pokémon gaming, the PokéAni is certainly a great way to tell us the villain teams in games, as they showcase the main villains of the core games. It seems like the ani-department was waiting for the gaming department to reveal them the villains teams of 'Pokémon Z'.
Most likely that will be covered in the XY & Z saga, but I'll not further elaborate as that topic is crossing this section's line.
That is no rush my friend. :) If this Gen VI game is going to lack post-game features like XY/ORAS, then I can assure you the Gen VI hype is gonna die shortly, like a month or three after its release. :P
I'm not sure if you noticed this as well, but Game Freak is slow when it comes to making use of the latest installment. Let me give you a little rundown for the consoles and corresponding game to help us determine the speculations:
- While Gen I games can be played in GBC, they were actually released for GB. The first Gen I pairs were available in year 1996, while GB was first available in Japan in 1989.
- Gold and Silver, the official Game Boy Color games were released in 1999 and GBC was made available in 1998.
- Ruby and Sapphire versions were released in 2002 and Game Boy Advance was available in year 2001.
And things are noticeably slow starting from Gen IV.
- While Nintendo DS, aka DS Phat unofficially, was made released in 2004. That was the year for Emerald, LeafGreen and FireRed's release! Diamond and Pearl were released in year 2006, it was even later than DS Lite's release. Arguably DP is for DS Lite than DS Phat, thus in a sense they released nothing for DS Phat.
- DSi was released in 2008, roughly a year earlier than HeartGold and SoulSilver's release. While the aforementioned titles didn't really take advantage of DSi, all non-events Pokémon can be obtained without the help of a GBA game pak.
- The first Pokémon core game(s) to take advantage of DSi were released in year 2010, Black and White. While their sequels were released in 2012, 3DS was already available in 2011! The ironic fact that Dream Radar, B2W2's related app, is available for 3DS while the main games aren't for obvious reasons.
- Finally X and Y are in our hands nowadays, which were released globally in 2013.
- The next game(s) we're speculating in this thread? They are surely not for NX! I don't believe it's possible for New Nintendo 3DS either to keep it fully compatible/similar with the current Gen VI games we have.
- Therefore, Gen 7 is mostly released under N3DS. ~So let's not hyped up for a NX yet, as there's none for New Nintendo 3DS yet!
