Liquidating your entire position based off of an unreliable source (especially at lower numbers and with regards to non-hardcore games) does not seem to be a wise decision. Especially when this game has yet to be released in Europe and PAL territories. This is an over-reaction to a guess made by an unsourced site. It is very likely that this game will slowly sell its way to over half a million copies, as pointed out here and here.
