You are undfair... Zorro2/3 is in it's own a limiting factor. For those who realy need massive expanded systems they will most likely sit with a tower conversion already and the Prometheus would not be a problem then.
Ask yourself what you need for the A3000D... scsi controller and scandoubler on board. Fast and cheap graphiccard and ethernet for the PCI... there's still one zorro or pci slot left if you want an IDE controller, USB controller, flashcard, soundcard or the like but if you want more you probably want a tower aswell anyway.
For the A4000D you won't lose any slots so there's no problem at that end and for tower conversions you will in fact gain some slots.
So please be fair. It still is a sweet way of giving the Amiga fast and cheap graphic and ethernet cards even if it is "just" a Prometheus card.
Ehm.. wait... need to promote Mediator also.. buy one, buy one, buy one... there, now I'm done. ;-)
