Oh, for heavens sake grow up kids!
This won't happen, not ever hopefully.
I have not signed, and I will not. This is why:
The current licensing scheme'll insure that AOS4 won't be pirated as every piece of hardware capable of running AOS4 will be sold with a copy of it.
If it becomes possible to buy a separate copy of AOS4, some idiot'll surely start churning out piratecopies of it. This'll result in a salesdrop of AOS4 and Amiga Inc. will propably soon go out of buisness because of it.
I ask you now, is this what you want to happen?
