Wow, a lot of people got it wrong.
I see every single poster on the first page overestimated by at least 50%, including 4 mods. Hmmm.
Here are some predictions from me:
1) Second week sales will drop by more than 60% to below 100,000
2) This game is overstocked in Japan. Expect bigger stores to start discounting it.
