Will Krita be able to import adobe ps brushes sometime in the future? I'm exploring both Krita and Affinity (50 euro), and the latter has that feature, which is awesome because there are a lot of great free ps brushed out there.

Krita already supports extracting the brushmasks. We will not be able to give further support, as the abr format is undocumented, is binary(which means that examining it kinda looks like trying to read the weird code effect from the film The Matrix), and we do not have enough funds for it.

Krita is of course open source, so technically a volunteer could add it, but that's unlikely, due to the file format being binary.
