Well, it looks like Deoxys is gonna be in the game or something, as a part of something referred to as "Episode Delta" which I guess sounds pretty cool...BUT NOT AS COOL AS HOW HIS BATTLE THEME WILL SOUND LIKE REMIXED! If the claims of this game having every non-X/Y legend are true, then we can probably expect awesome remixes of quite a few awesome Legendary Battle themes in this game, which could include:
*Raikou/Entei/Suicune Battle Theme
*Ho-Oh Battle Theme
*Lugia Battle Theme
*Regi Battle Theme
*Groudon/Kyogre/Rayquaza Battle Theme
*Deoxys Battle Theme
*Sinnoh Legendary Pokemon Battle Theme
*Uxie/Azelf/Mesprit Battle Theme
*Dialga/Palkia Battle Theme
*Giratina Battle Theme
*Arceus Battle The- okay, this one's probably unlikelier than some others.
*Unova Legendary Battle Theme
*Reshiram/Zekrom Battle Theme
*Kyurem Battle Theme
...I think I might be more hyped for the OST than I am the actual game.
EDIT: NONE of the legendaries are getting remixed themes, aside from the Groudon/Kyogre/Rayquaza, and probably the Regis. And guess what? Deoxys does, indeed, get a remix to his theme. Don't worry, though, all the other legends still get their themes- they're just all ported from their original games.
and on another note, we have THE BEST NEW FEATURE SINCE POKEMON MYSTERY DUNGEON'S SKY JUKEBOX- ANOTHER JUKEBOX! It's apparently a secret base decoration And it's in-game description states:
"Jukebox - A machine that lets you listen to whatever music you like in the Secret Base."
But so far we only know of it from a text dump (heck, I don't even know what it does, or even if it's limited to certain music), so no known way to get it yet. I swear, though, if it's a reward for completing the Dex again...or, better yet, a Japanese-exclusive item...no, Xeno. Stay positive. They wouldn't try to screw you over that badly...nah, they probably will. T.T
