i simply dont see this as viable at all , i would love to mess with AAA and all that but i know why commodore and amiga + escom + gateway + tulip didnt go further into it , as it costs money!! and alot of it!.
we surely need something special in the next gen amiga's but i would say that instead of thinking about AAA (which is infact dated compared to the saturn's 2d and the playstation 1's 3d) we should instead ask ati/matrox/nvidia to do an AMIGA styled gfx chip/customs, they have the expertise and they are the ones who make the new standards, and as we all know everything in the pc world theese days ages rapidly.
Gc/xbox and ps2 got their own custom designs based on well known designs from the time they where built and improved , making new stuff from scratch would (i guess) make the consoles even expensiver + would put the creators in an money issue over time..
dont get me wrong, i am a big fan of amiga and its custom chips and i would love to see an AGA on PCI card or simmilar ways but thats just about as long as i would go for now.
Amiga needs money, amiga needs an os and most of all Amiga needs to rise in its potential market before we can dream about a new custom design.
we all know what happened to the A/box , BOXER and so on, diffrent designs i would love to have but as time went on it showed how hard it would be and most of all the kind of an budget you would need.
