That entire post applies to me as well. We've seen the Amiga decline over the last ten years. Gateway gave up on the "classic" platform completely. Amiga inc made the decision to restart development - that alone makes me respect them a bit.
As for OS4, you can work out quite a bit about it from what we have. The kernel works fine. The OS has been complete enough to give to 70 betatesters. The only remaining issue is emulation.
I'd prefer Hyperion to update us more, but if they have taken the decision not to - probably a good idea, considering how whatever they say can get torn to pieces.
