I doubt the OS can be "delayed" any longer by any action MAI logic can take. In fact MAI seams to like Hyperion, the conversations I had with Ben Hermans at AmiWest where very positive regarding MAI. I'm sure when the OS is done the work to support a 970 board should just be a matter of drivers. Given that similar drivers need to be created for the current shipping AmigaOne mobo's the work should proceed rapidly.
All that said I'm upbeat about Hyperions chances on releasing OS 4 for CSPPC this year and possibly a few months before Chrismas! I also think that OS 4 for AmigaOne will be available 2 to 3 months after OS 4 CSPPC. I'm guessing that when the smoke clears both MorphOS and OS 4 will be running on shipping 970 based product around the same time. Assuming both efforts still exist
