Since they wanted it to sell better and to a larger audience than DMC4, it does not seem that this game has sold 'well'. For it to have sold 'well' in the developer's view, it should have shifted more units in the first week of release than DMC4 did in the first week of its release, and for it to have sold what they wanted it should have shifted their initial projection of 5 million (which was a bit optimistic), or reached 1.2 million (which it will eventually). But like Hollywood the games industry sets targets for the first week and month, because they want people buying units at full price, not waiting for bargains or 2nd hand copies or rentals.
