Here's a quote from my previous post.
As I previously said, with GIMP 2.4 coming out soon, there's supposed to be support for PS brushes. I'm not sure to what level, they'll be supported, but we shall see. If it's full support, then the conversion process will come to an end. But, if it's limited support, I'll continue to convert/post brushes as the feeling hits.
You can also read this journal entry at dA where I also discussed why I continued with the conversions:
