Well to put it in a simple way:
Minimig = A500 equivalent (has been for sale for a long time)
*Arcade FPGA = A1200/4000 equivalent (available soon) http://www.fpgaarcade.com
Natami = 
*More or less, the Arcade FPGA is the equivalent of an A1200 with:
CPU 68020 @ 100 (and this will get even better with the next core)
64 MB of RAM
2 x HDD (through .hdf file on SD Card)
4 x Floppy drives (through .adf files on SD Card)
Indivision (though onboard DVI)
What price range do we talk about, will it(ArcadeFPGA) come boxed in a type of case/tower?
i have seen the minimig at amigakit.co.uk now, i was somewhat put off by the price for a complete setup and not just the card/mobo, i never expected it to be really cheap but i also didnt expect the cost to be spread over so many items either.
That said, the minimig ecs/ocs thing is really interesting although not where i want to land my cash, AGA is what i need for my games so i will buy one as soon as its out.
Really intrigued by the daughter board etc and i got several 060's laying about as i've burnt a few bPPC's over time sadly :-(.
Will boot times and load times etc be the same as orginal Amigahw or will it be accelerated (like UAE does).
Will CD only games work, like OnEscapee,Napalm,T-Zer0 etc? (i did see that hdfiles are supported so i guess they will.
Which filesystems do they use?, which GB limit on bootable device partition etc?
ETA?, before summer or after?
Resellers ?
video manual?
Kickstarts? (will the os4.1upd4 kickstart's set which is included there work?)
thanks for your time.
