Go really isn't "traditionally" played on 9x9 and 13x13. They where introduced in recent times to make teaching easier. The traditional board sizes are 17x17 and 19x19. The reason for odd sizes is simple: even sizes lag a tengen which is quite an important point for symmetry and philosophical reasons. A Go board lacking the "center of the universe" isn't really a universe (= Go Board). 

A "virtual" point symmetric point doesn't count. And symmetry is quite an important aspect in chinese philosophy. I know, Japanese like asymmetry more, that's the primary reason why they got rid of the traditional 4 stone setup, but they won't get so far to dare to remove the center of the universe.
