Well, one could argue:
"Because, for the first time in the 21 year history of TIFF, the structure itself has changed, and, accordingly, the 'version number' has changed from 42 to 43. (The 'version number' has, of course, been 42 since the very beginning of TIFF.) This breaks all existing TIFF readers."
There are admittedly 'political/marketing' advantages of keeping the name as just "TIFF(.tif)". But I think that users will be very frustrated in dealing with a ".tif" file that no software created before 2008 can read. This sort of thing tends to damage TIFF's reputation as an interchange format.
FWIW, Adobe Photoshop calls it's new > 2GB files ".psb" files instead of ".psd".
Best regards,
Stephen

90% of the programs out there can't handle tiles, or 16-bit images, or layers, or JPEG compression, or LogLuv compression, etc, which are all valid TIFF files - why is this any different?
