This made me chuckle too:
"Over the next 5 years you will see OS 4, 5, and version 6 in the market along with supporting builds and infrastructure across several digital devices."
However the question was basically asking - Do you have a roadmap? So I guess they do and there it is. Whether it happens or not who knows!
And I guess I don't care much anymore. I will always be interested in what happens with the amiga OS but I doubt i'll end up buying a new amiga because the soundcards I use for recording (creamware) will never run on an amiga.
