Well, I mean the only history with the mainline Kingdom Hearts games is that they both sold over a million in Japan, so I'd say that greatly supports my outlook. I don't think VII will make it to XIII levels, i just think it will cross a million.
Oh wait, you're right. I got numbers flipped in my head! I was thinking 700k, but I checked. At least KH2 sold 1.1m. KH1 still didn't though.
Then again, that was also PS2, so... >.>
