Well, since nobody asked for my opinion, here is MY dream scenario:
Apparently, one mans dream is another mans nightmare.
Microsoft suddenly has a change of heart and invests all their profit into CUSA and Workbench 5.
And then they bring back Amiga Basic, but this time it always fires requesters: "This Basic Programm wants to connect to the internet. The internet can be harmful to your computer, do you want to (C)onnect or (A)bort?" And will prompt "You can turn off your Amiga now" when you quit Workbench.
... and sues Aros out of existence a la SCO.
And while they are at it, they eliminate Linux by suing Torvalds about his first name?
100% backwards compatible with all existing Amiga software
Especially Word Perfect and IBM Transformer.
