The existing Amiga architecture does not have the bandwidth to support more
then 640x400x4 interlaced (+ overscan).   If there are to be some new chips
that support non-interlaced video, I don't think they could overcome this 
limit. They would therefore be limited to 640x400x2 non-interlaced.  That 
would provide only 4 colors.  

As a side note, the flicker-fixer by Microway can display the full number of
non-interlaced colors because they provide an alternate, higher bandwidth, 
video output.

Disclaimer:  I am a beta tester for Microway's flicker-fixer.
