I don't want to step onto JayWood's territory but are we already talking about a flop ?
In japan, during the same time period as DMC 4, DmC sold half as much* (on the PS3 alone, far worse on the 360)
In the UK, during the same time period as DMC 4, DmC sold just one third what DMC 4 did.
Note the absence of any other major title launching at the same time.
*While DMC 4 and DmC pre sales were the same, meaning Capcom failed to attract their goal, the casuals.
To this day:
DMC HD Collection: 0.74 m
