While it did originally seem that focus was going to be/was on finishing the English translation for Johto and the post Johto DLC, that was eventually shifted to now focusing on completing Hoenn in Spanish (including making all the maps and scripting all the events and everything else).
So while the original impression was that the only thing that needed to be completed was Johto and the DLC's English translation and playtesting to make sure it was inserted correctly, which (as stated in the opening post) would have/was originally said to be done within 3 months of the original English release, this shift in focus means that it will take longer for the next English release of this game to be finished.
And again, that's because of the shift in focus. It seems they want to complete the game/the next portion of the game in Spanish, first. (Which they're basically building from scratch, since they don't have vanilla aspects to work off of.) Then, once that's been completed, they'll go back to working on the English translation and playtesting.
We can no longer go by what was originally said and inclined, but by what the current plans/focus has currently shifted to.
