Professional Photoshop users needed 64 bit TIFF now. Some high-end print users needed it about 3 years ago.

I would break the possibilities down farther:

  1. break with existing and keep as much compatibility as possible
  2. break with existing and keep only the good ideas, but not value compatibility (meaning that tag values will change, and we can clean out some cruft)

Some people have suggested that ASCII based tags would make debugging far easier - and if we're going to 64 bit values we can use 8 byte tags as well.

tag: 'ICCProfl', 'Compress', etc.
