Will there ever be a manga for Kingdom Hearts brith by sleep

I haven't heard anything about it but I'm almost 100% sure that Shiro Amano will keep making the manga for the Kingdom Hearts series. I don't know about a non-Japanese release or anything but I know that Square Enix has a magazine-based manga magazine called Monthly Shōnen Ganganthat has Square Enix Manga adaptations by different artists.
358/2 days is an example of one of the current manga in Monthly Shōnen Gangan.
If you're looking for English versions, they DO have those all over the internet. Go to sites like OneManga.com. They have 358/2 Days translated already :)
