More evidence against Hoenn is that in Japan they're giving away tons of Gen3 pokemon:
Nobunga's Rayquaza, Kyogre, Groudon, Metagross, Sceptile, etc. all on the new bullet trains. Why would they give away all the gen 3 legends for free if they were planning to release access to them through a trip to Hoenn?
The MOST plausible thing I can think of (and I'm still extremely skeptical about it) is "a few years later" scenario. Maybe a surprise appearance by Team Magma/Aqua since Plasma is 'gone'.
A few years later you start a new adventure, retrace your old steps, and face yourself as the champion much later?
