There may have been some software issues with the Bridge Cards, the A3000, and
perhaps 2.0.  But I've used them, they work good.

That's silly.  PClones always talk to their disk, keyboard, and video display
via an 8 or 16 bit bus.  That's all the Bridge Card does with the Amiga, at
worst.  It's not like the Bridge Cards has to cross the Amiga's expansion
bus to get to its program memory or anything like that.  And as I pointed out,
most PC applications use the '386 as simply a faster 8086/88 anyway.  A '386
bridge card would make sense.

>For VGA, one really wants the fastest transfer possible -- and that's ZorroIII

That's true, a full 32 bit Bridge Card would make much more sense as a Zorro 
III device.  It would certainly pay to make one which could act as a Zorro III
bus master, further improving thoughput.  But there are certainly more Zorro II
machines out there, so they would have to consider that aspect as well.
