So I'm not the only one noticing Hoenn references? I've come across 5 references to Lava Ridge Town, and on the second floor of the Richissime Hotel in Lumiose City, and elderly couple is in a room, when you speak the woman she says that their first date was the Oceanic Museum (Slateport) and when you speak to the man he says "The 40th anniversary is Ruby, the 45th is Sapphire"
I know speculation isn't allowed to be discussed on this site, but I literally squealed with delight when I saw that. Generation 3 and the Hoenn region were my favorites, and the possibility that they're going to be remade in the breath-takingly beautiful quality of generation 6 and the Kalos region made me absolutely ecstatic
There are plenty of references to almost every region when you're not just looking for Hoenn ones. I've seen Sinnoh and Unova referenced multiple times, and I believe Kanto and Johto as well.
