>>18094160Z seems most likely. They usually release the third version as a way of fixing all the errors of the original two games. But since they couldn't improve on Black/White without majorly changing the region they made BW2 (also I think they were told to do something different if they weren't making a 3DS game). X/Y have plenty of things that need improving so you can expect a Z version with less framedrops, more post-game and a purpose for Zygarde.
Then Ruby/Sapphire remakes will probably come after that. Although since games in the same gen take place at the same time (Emerald takes place at the same time as FR/LG, Platinum takes place at the same time as HG/SS), a sequel seems much more likely. This would be a good chance to turn Hoenn from a good region to an amazing region.
