So I wonder what it is that would make all of these "It's not really an amiga!!!!" people happy?
Let me imagine...
-A new AMIGA video chipset with all of the best features of NV20+ and Radeon 9xxx, plus BACKWARD AGA COMPATIBILITY!!!
-some bus more advanced/faster than PCI-X, that transmits 40 GB/s
-Audigy+ level audio,
-Optical chip interconnects,
-USB 2.0, Firewire
-Amiga-specific keyboards and mice,
-A new, incompatible DVD/RW format (which would be faster and more 'elegant'), so we can be different and better
-Brainwave detection software so you can think instead of type
In short, (mostly)stuff that you can't buy on a PC Motherboard, but would be so frickin' cool that no PC user would be able to resist buying... if the price were anywhere near reasonable.
Unfortunately it wouldn't be, because AMIGA would have to do all of the R&D, engineering, production ramp-up, marketing, sales and support. Which means that they'd have to price the board at TWICE (or more) the price of an A1. Not to mention the fact that such an effort costs HUNDREDS OF MILLIONS OF DOLLARS, which Amiga has a mere sub-fraction of in the bank.
I cherish the idea of Amiga hardware being different, but not at the cost of being able to buy one. This isn't 1985 anymore, kids.
If amiga wants to control their platform and keep it consistent(one of the aims of making a "custom" MB in the first place), they don't need to build a motherboard that has every possible unique feature on it. They need to spec one that works well and has acceptable speed and features. THEN, when they have a little more money in their pocketses (sorry, J.R.R.), they can design something more like what the naysayers are looking for.
Remember, the idea for OS5 is to be hardware-independent so you can use whatever type of motherboard you like. Be happy that you can buy something called an Amiga, and not a windows box that you run an emulation on.
Don't like it? Build your own and find out how difficult/expensive it is to create a hardware platform from scratch like you suggest Amiga Inc. do. Then come back and let us all know how far you got.
