So I've read the fully translated interviews with
Famitsu and
Dengeki Playstation on KHInsider.
First off, I think I saw a Famitsu summary posted here earlier that said there would be no further information until 2018. This seems to be a mistranslation. There
will be
"another small intermission" in news. In a separate statement, Nomura recommends that
"up until the 2018 release there’s some idle time, so please fill that up by playing the HD remasters and Union Cross"
So... still plenty of opportunity to give more details within this year.
Some details also caught my interest in the Dengeki interview.
First, Twilight Town is visited early on, with some gameplay tutorials.
Secondly, Nomura explains that while he liked going to worlds twice in KH2, KH3 has a different flow.
