Sony have announced they are going to be using GNU Step for their future products... That could inject some vital development money/time into the project!
I'm wondering if Sony are hoping to cash in on the number of new Obj-C coders who have grown up around the Apple ecosystem? It seems like a slightly odd choice to me, but not a bad one!
Now, where is our Amiga GNUStep port? The Amiga seriously lacks an objective-c runtime for those who would use it
