There might be future changes to GRASS which would make this difficult 
with the current version of GRASS (e.g. plans to change the raster 
format / storage organisation). However, you will always have access to 
older versions of GRASS GIS and so should at least always be able to 
open old mapsets in those and then update if necessary.

Otherwise, I think that well-compressed tiff files will remain readable 
for quite a long time.
