Opportunity cost, possibly. They might be remastering it and wish to sell it at a higher cost, or think they can get more money through a different retailer.
That game seems pretty loved, I wouldn't be that surprised about a remaster. Though it would have to be a pretty barebones if it can't compete with a ten year old release.
A lot of publishers remove the original game when they release a 'remaster'. Burnout Paradise, Metro Last Light, etc
