Why would there be "a wave" of new software because it's faster ? Winuae is also a fast 68k machine in some way did that change a lot in 68k programming ?

If the thing is *REALLY* stable, a PPC accelerator would be great tough... but in such a small market where there are already other hardware options for the next-gen AmigaPPC OS, a PPC accelerator for a yet to be finished 68k Amiga probably isn't going to happen fast.
