I don't see that much use in a new 68k "classic" because of the lack of really improved performance compared with existing "classic" Amigas.
But something I'd indeed consider cool and lacking besides Pegasos/A1 would be a true Amiga home computer again - not necessarily a high-end PPC CPU but some "custom" hardware on-board already for certain multimedia capabilities.
Would be no device to change to for current desktop users, obviously - but given the AmigaOS's intuitiveness and user-friendlyness, it might be a nice machine for those who don't own a computer yet and wouldn't use it for much more than writing a letter or club magazine besides the board's multimedia stuff.
To put it in a nutshell: while we do have already continued the x000 Amiga models by the Pegasos and A1, also having a x00 Amiga again would be nice, IMHO, too.
