In case you are not aware of this, Adobe owns the TIFF format. They got it when they acquired another company (if I remember correctly, Aldus). The latest specification is TIFF 6, available on the Adobe website.
The issue with updating TIFF to use images larger than 4GB is that the TIFF tags are a fixed 12 byte format with many of them using an unsigned 32-bit value for the image size. It would require some clever work to make a newer file format backward compatible yet allow for larger images. There is also the issue of all the third party extensions TIFF has received over the last two decades and keeping any new TIFF format compatible with them.
