How do I know? I conclude it from the fact that apparently, most of the dev staff is working on it. Comparatively few resources went into 9.5 (not to be little those efforts, but it is just visible that the devs were trying to be economical here).
That and knowing what the team pulled off in past seasons, and with the LoR expansion, makes me very optimistic.
What will it be? I don't know. But some kind of exploration seems like a safe bet, doesn't it. More Delta quadrant sector maps? Probably.
Of course, there will also be another lockbox. Delta-quadrant-themed. Borg? Krenim? Who knows.
One can only hope. Hopefully something a bit different from what we have now, like a robust and interesting exploration system. Or some randomly generated style STF system so its not the same old fights all the time. That would be great.
