It's supposed to be "why did IT choose you!?".
Hahah, yeah. Though that wasn't the only mistranslation, though. Dilin (instead of Dilan) and Bleig (instead of Braig) were part of the hurried and pressured KH2 localization mistranslations (that rhymed).
Doubt it. Like stated in the KH3D to PS4 thread, the entirety of SE is very busy.
-Birth By Sleep isn't terribly ported
Yes, please. :v
maybe even a sneak preview of the next saga should it come out after KH3?
Doubt it. If KH2.5 has a secret ending, it should lead to some new footage pertaining to KH3, while KH3 covers footage for the next saga.
- Riku playthrough starting where we left off in CoM (not likely, but would be awesome)
How would this work, though? It would be a very linear game, seeing as how there's not much to cover except things we already know he and Mickey did in a playable form (which, personally, is a waste of time and resources). All that extra effort for an extra scenario should be used for an online Mirage Arena. :>
- More Roxas playtime, maybe start before the 7 days in digital twilight town? (Riku vs Roxas fight anyone?)
Yep, this makes sense. Start KH2 right at the moment where Roxas kills some Neoshadows (playable), confronts Riku (cutscene), they both kill Heartless (playable), they start fighting each other (playable), he turns into Ansem, you fight him, but even though you win or lose, it still carries on to Roxas getting beat up by him.
- More areas to explore (like Radiant Garden's castle)
KH2FM already covers this.
- Co-op/splitscreen story mode where you can go online and play through the story with friends, the host would be Sora and the people who join could play as Donald/Goofy/World Specific Character... It'd be a fun and different way to play through the story again, plus you'd get to do it with friends.
This would be too big of an overhaul and power they could use instead for, as mentioned before, an online Mirage Arena. And seriously, an online Mirage Arena would keep fans busy until the release of KH3.
- Mickey Playthrough (the guy did a lot, it's not likely but would be awesome)
Is there a need besides fun in terms of plot?
- CAPES CAPES CAPES... YOU HEAR US NOMURA???
At least for the final battle because when they ride their Keyblade vehicles they would look dumb.
- BbS v2 is added to game somehow
Is there a need for a game that ties BbS and KH1?
- Playable Lea vs Ventus fight
Yes, I thought that was an actually boss battle, but no.
- Revisit worlds after beating game (playable DI anyone?)
They can also add some chests here and there.
- The option to replay boss fights
Yes.
Besides the new ones from the FM versions, no cigar.
- New secret ending, teaser for KH3
Yes.
