Kana Asumi tweeted out about the new leaf Nep game the other day, and Compile Heart re-tweeted her. If she's involved then it's pretty safe to say that the four main girls are going to be in it, since I can't imagine they'd hire her but not Asami Imai and Rina Sato. And if they are all in, that significantly elevates the chances of the Mk2 crew appearing as well. So the roster is apparently already starting to crystallize. twitter.com/0812asumikana/status/972781591838670848
Also the leafs making might be going "2D side-scrolling RPG" with this rather than a platformer, based on social media mining that's been done so far. This would fit in with the "every game an RPG this year" news post from a few weeks back. As far as political issues (since that seems to be people's concern at the moment), on that note I haven't heard anything within that stuff yet one way or another, but that doesn't mean that can't change in the future either.
