VGChartz is not a reliable source of information. If you compare many of their sales figures to official ones, they tend to be off. Official sales figures from companies have to be correct or the companies can be pursued for fraud for reporting more sales than they actually made IIRC, whereas VGChartz has no such restriction or oversight. So it isn't what I would consider a valid source of information. And in any case, they don't post sales projections, or sales after 1 fiscal year so there's no reason for me to use them.
Also, the 5 million thing is myth perpetuated by mainly opponents of DmC to expose Capcom's supposed hubris. It originated from
this article where Motohide Eshiro, a producer and not a corporate officer with any hand in planning the marketing or sales, said:
That's the only mention of the 5 million units thing, that's it. He doesn't even say they want 4 or 5 million copies or that they hope for them as if it is in the realm of possibility. He is only implying that they would like to capture the larger market share that these more successful action games have, and I assume he means GOW. It did not constitute an official or even unofficial sales projection in any way, shape, or form, although opponents instantly latched onto it and twisted it into "Capcom says DmC is going to sell 5 million."
The purpose of my post was just to compare the projections to actual sales, to show that the DmC projections are reasonable and that Capcom has a good track record with meeting or surpassing their projections. So I fully expect it to sell 2 million, if not more.
