You know the score with a NDA - you can't discuss it. If there has been a hold up, you can be sure someone knows why, but be sure that they won't say anything.
When something can be said publically, it will be. Until then, the latest noise is that as RiscStation's hardware partner won't give them a date for completion (due to them not being given a firm date by their suppliers), they are not saying anything publically about a prospective date.
That should also be in your archives.
Perhaps you're now trying sooooo hard to be El Reg for RISC OS, some things have slipped your attention
