I don't know yet whether this is good or bad news, but it seems the AmigaOne and OS4 are not affected by the sale. Amiga Inc. never really seemed interested in the classic Amiga OS anyway, so I don't miss those guys. Eyetech and Hyperion were the ones who worked on the future of the real Amiga platform, the Amiga DE has absolutely nothing to do with the Amiga and has never interested me (or any Amigans that I know) at all.
I understand why Amiga Inc. sold the Amiga OS'es, but I must admit I'm wondering why KMOS bought them. What are they planning to do (I mean, beyond OS 4)? And who are they anyway?
