Considering that KH3D uses more or less the same engine as BBS, it wouldn't be that hard. Another point to consider is that, along Days and Re:Coded, BBS is essential for the understanding of KH3D, even more essential than the other two. So having the portable "trio" playable on the same console wouldn't be that bad.
It talks about BBS being ported to 3DS.
Why do you think?
