I bet in a month prices come back down to msrp. I don't know. I mean the game has only been out for just over a year so I don't think there was more than one print run. If there is more pent up desire than the limited supply, I don't expect prices to drop.
Plus the number of people who are interested in a copy will only grow over time. Things like being in Tom's Top 100 (it was 74 last year so it might stick around) will continue to bring late comers seeking the game.
