Historically, 25th anniversary collections have been hot sellers. Just look at Mario All-Stars. I expect this to be limited in printing and to gradually rise in price. Though hard to tell if the ps3 or xbox versions will be more desirable, but I would say ps3, because of the blu-ray discs being playable on the ps3.
Correct me if I'm wrong, but the 360 version's bonus discs (anime, documentary, etc), do they come on regular DVDs or blu-rays?
