I think a good measuring stick for what happens to prices on reprints of highly playable cards is Birds of Paradise. At Starcity a revised BOP is $16, a Ravnica BOP is $17.50, and a Beta BOP is $200.00. I think that this shows that the pimp version of a playable card tends to hold its value. And BOP has been printed in every set except 9th.
Regarding printing FOW in a theme deck, I think the biggest factor Wizards is going to consider is whether or not they want to release it into the Magic Online Classic format.
