By way of NeoGAF, from Bloomberg.jp:
For PS3 sale of software “NINJA GAIDEN ##” worldwide was favorable. In the country June, in Europe and America sale was started in July, you say that 450,000 book was already sold. As for annual sale plan 500,000 book. As for “the NIJA GAIDEN” series in the past, selling in for X box, the hit work which sells 1,500,000 book. For PS this time the first time.
So, 450k shipped, and they want 50k more shipped. NG on Xbox sold 1.5m...Not too shabby.
450k to retailers is a pretty big bit (as they're guarenteed to sell that many, since they won't just....dump the games). Good job, NGS deserves its sales.
Back from the dead, I'm afraid.
