Most software should not break. This is the great beauty of the Amiga's OS! 

If you did not do any dirty and *unsupported* tricks, then everything is
guaranteed to work on the next version of the OS. The interface does not
change, merely the implementation or the CPU underneath it. And Commodore
will worry about that for you. 

For example, one of the earliest games for the Amiga was MindWalker.  It
works under 1.0 to 1.3 (and, I bet, under 1.4) with hard disk support,
multitasking and fast RAM support right from the beginning. Why? Because 
it followed the rules. Games that are not as well behaved as MindWalker 
must have some kludges in them in the first place. 

So, building new machines with 68020's or better should not be a
problem. Of course, the 68000's will also get cheaper, so why switch for
older machines? This is what C= is doing, in fact. The 3000 will have a
newer CPU and the older machines won't, and everything will be
compatible. And everyone will live happily ever after. (well, in theory
at least ;-)

IMHO, for these and many other reasons the Amiga's OS is one of the most 
well designed OS's you can buy.  (yes, including the DOS part -- try doing 
"crossdos" like things as easily on any other OS)

enough ranting
