Hopefully they mean version 1.0 exclusively will have 239 total scenes, meaning they'll add 239 to the existing 209 (totaling to 448).
Granted each waifu has 40 slots total right now, which sums up to 360, which even accounting for 40 slots for an extra waifu (ie Fow-chan) it'd be more than what we'd expect with the spare slots we've seen.
Hopefully it'll be that, considering it's been over half a year (at least it feels like that, might be wrong on the time).
Otherwise, this will be a bit disappointing seeing how long its been.
