That is a sensationalist article. This is a sales site. I encourage users to check the numbers:
DMC4 week 1/2 sales: http://www.vgchartz.com/weekly/39481/Global/
DmC week 1 sales: http://www.vgchartz.com/weekly/41294/Global/
Year on year sales are down. This game is coming in at the end of the console cycle.
And DMC4 had much weaker competition.
Capcom made those sales predictions last year assuming the game would enter the market in the same conditions as DMC4.
The point is its just a bad time to release a new IP or a reboot. DmC has actually done pretty well in my opinion. What Capcom need to do now is release a special edition of the game next year in the same conditions DMC4 entered the market. Because this game isn't about DMC fans buying the game, its about getting new players to do that. New players WILL NOT buy this game at this point in the console cycle.
Personally I think the sales are good, not great, not bad, but good!
