I don't remember hearing/reading a schedule commitment. Maybe a long time ago they wrote "later this year", but that would have been a generic "later" from the marketing department, rather than a firm engineering schedule.
Personally, I think the most interesting thing will be to see if/when developers release their libs with GVI players. Winter NAMM is just around the corner. Hopefully, we'll hear some news there, as I'm starting to think seriously about taking my libs to the next level. Maybe we'll get an update on the Mac release plans then too.
