How many of you think this is a sign that they will eventually reprint it in real life?
The reprint is much more badly needed on MTGO.
Paper, Force of Will isn't the big expense for Legacy, it's dual lands (and to a lesser extent Tarmogoyf and Wasteland but they are high on MTGO too). But in MTGO, dual lands are in much higher print (each one rare in two ME sets) than Force of Will (rare in only one ME set, with a firm promise made not to reprint it in a booster product).
A 40-50% drop in FoW's price on MTGO would make Legacy much more viable online. In doing so it would push up interest in other format staples like dual lands, both fetchlands, Wasteland and the like, probably increasing the total value of most players' and dealers' collections (except for those few that own four foil Force of Wills).
OTOH a paper 40-50% fall in Force's price would have little impact in Legacy's overall price as a format or its appeal.
I love this promo, but why have we all of a sudden, gotten an awesome promo for this season? I'm not complaining at all as this seems like such a great thing for legacy players or for people to get into this format, but why hasn't there been a promo like this before? Every other QP I've qualified for has given us 2-3 dollar rares like Sol Ring.
