The Japanese retailer Yodobashi has some images on their product listing which confirms several new features and extras for the upcoming HD Remaster: http://www.yodobashi.com/ec/product/100000001001668276/index.html
It can be hard to make out since they're really small, but here are the details.
Kingdom Hearts Final Mix
- You can switch between English voices with Japanese subtitles or Japanese voices. This wasn't possible in the original KHFM release.
- Completing the game will unlock a PS3 Custom Theme.
- Trophies (already confirmed previously).
- EXP Zero and Combo Master abilities are added to the game.
- The Talk and Special Attack Commands have been remapped (to the triangle button I think, previously confirmed by the trailer).
- Full camera control on the right analog stick.
- The summon command has also been changed somewhat, but it's not specified how.
Re:Chain of Memories
- Trophies (zzzzzz).
- Completing the game will unlock another PS3 Custom Theme.
358/2 Days Theater
- Over 2 hours of cutscenes completely remade in HD and fully voiced (woo, ice cream...).
- All of Roxas' diary entries, the Secret Reports, and the Character Database are all included as well. Won't want anyone to miss out on the AWESOME story details amirite?! Lulz.
- There's also a PS3 Custom Theme reward for this, I think after you watch all the crap.
