What would you want the next Amiga to be?

[MskoDestny]

My dream "new Amiga" would be something like this:

Fastest ColdFire CPU
PCI, Ethernet, USB, ATA (or SATA) with DMA
256MB+ Fast, 64MB+ Chip mem
Enhanced AGA compatible chipset in FPGA with the following features:
  Supports all "classic" modes
  Chunky and 16/24/32 depth modes
  Limited 3D support similar to what's in the Sega Saturn (deformed sprites are used as quads to make 3D models)
Classic joystic ports, but hardware support for making USB joystics and mice appear to be available via legacy means so they can be used by hardware banging software
Proper 68000 (or 020 or 030) for booting into a "compatability" mode (possibly integrated into FPGA)
Low level floppy emulation using images on the hard drive

For an OS I'd like to be able to dual boot into AROS and Syllable ( http://www.syllable.org/ ). AROS for running old Amiga software and the full "Amiga experience" and Syllable for an OS that I'd actually like to use for day to day stuff. Of course, at the moment neither of these OSes have working 68K ports, but then again the hardware I described is complete fantasy too. Theoretically classic Amiga OS should run in "compatability mode" if not on the ColdFire with JIT.

Why? Just emulate the 68k... there is pretty much no way you could push a 68k much faster than the 68060... the architecture is just too CISC for high speeds...

That hasn't stopped x86. On modern CPUs RISC doesn't buy you much anymore. The die space needed for the extra front end complexity is insignificant on a modern desktop CPU and even the RISC processors have some front end translation going on now.

I doubt there ever will be a high performance 68K processor, but the reasons for that are economic not technical.

Anyway, while your question was directed at someone else, the reason I would want a real 68K (or at least a close cousin of the 68K like the ColdFire) is because I don't really want an Amiga for any real practical purpose. A bog standard x86 PC running a non-Amiga OS does that fine. I just find the Amiga hardware neat and I think the 68K family of processors is also quite cool. I essentially want a geek toy, not a practical machine that will bring Amiga back as a contender on the desktop.
