AmigaOS3.999 or OS4 for 68k?

[alx]

To begin with, remember that the new kernel certainly won't be able to be ported to 68k - it definitely wouldn't be OS4.  And Amigans would certainly be laughed at if the new OS (or even part of it) would run on ancient 68k processors.

The world has not stood still - but the Amiga has.  IMO we simply cannot expect a new OS to run on early 90's hardware.  "Classic" Amigas are falling to bits, and we need a clean break from the past.  Of course, you can still upgrade them to PPC to run it - what other new OS would you upgrade from 60 to 200Mhz to use it :-)  Perhaps the naming of OS3.9 was deliberate - aside from a recurring decimal, nothing else could have indicated better that it was the last ever 3.x OS.

Besides, there are other issues - I doubt that Hyperion would have the resources to co-ordinate and support OS3.9999 or whatever.

It runs on 68k belive me

I have OS4 betatester friend, who testing the OS on his Classic Amiga with 060 + Gfx card. And making locales for the OS.

Oh no it doesn't ;-)

OS4 is made up of lots of modules.  Some of them are unchanged, such as the Workbench.  Others are very different or new, such as AmigaInput.  The lowest level part of any OS is the kernel (eg the Linux kernel).  The new kernel for OS4 is called ExecSG, and as jeffimix said, this will only run on PPC.  AFAIK what the (lucky) betatesters have is various modules compiled for 68k - the kernel itself will never be 68k, and as a consequence OS4 will never be 68k.  The modules certainly could be kept as 68k, but I really don't think they will be.
