Once a year TAR for me is okay... There are other versions to fill my heart.
And they can pool the budget to make seasons better!
Also I'm thinking CBS could rotate between the 3 big Reality-Comp shows every year like this:
September to December - Survivor
January to March - The Amazing Race
March to June - Survivor
June to September - Big Brother
Maybe they could market this like a reality-competition time slot, though I don't know if they've tried this before...
MAYBE they could even make the finales of each one lead in to the premieres of the next one...
But honestly the thing that makes this very unlikely is CBS having to push Survivor from late Feb to Late March
