500-1 mil range sounds right. I'll go 800k to be more exact.

Hopefully below 500k.

Depends how well it reviews!

Well, looks like 500k-1m is easily the most popular choice. 

Will be bumping this in a year's time or so and we'll see how we did. ;)

Below 500k. Nobody has asked for it.

Is very likely to become a million seller.

I'm hoping that even though it shares resemblances to Sticker Star, they learned from the criticism. I know I won't decide whether to get it until I've read opinions and reviews, from critics and gamers.

If it has improved over Sticker Star 1-1.5 mil, maybe more if it's really good.

If it's Sticker Star 2.0, 500K to 1 mil (because it's still all Nintendo has this holiday season).
