Reported on neogaf translated from a Japanese website here:
The new issue of a famitsu claims Bb cp is coming to Vita. Will also share DLC with the ps3 version
So you don’t have to rebuy Kokonoe.
No news on if it’s cross-play, but will keep my fingers crossed.
Also no confirmation it will be localized.
P.s. It was strange to not see this news here so lock and delete if already reported.
