My buddy only pre-orders by amazon. I told him about the free DLC at gamestop and I went to check if it was mentioned somewhere on Amazon.
I noticed the Amazon best seller rank in the details fo DmC. rank #1300s in video games. I though 1300s seems pretty bad, I'm going to compare later tonight, which I just did!

I wouldn't bet by savings on it (Vegas would love that) and the sample is rather thin. DmC DOESN'T offer Vergil DLC with amazon which most probably lower its pre-order rank... DmC is the only game of those being released in Jan, I guess the closer you are to release the most pre-orders you get.
My conclusion... it should be within top 10 if it was showing on VGchartz. I can already forget the idea of an effortless top tier score on the leaderboards, as I did in NG3.
