I think it's safe to assume it'll be a Nintendo game... Probably a DS or 3DS game, and depending on sales we might see a Wii U game enter that list later on. As I've said before; Wii U will have one 10m+ game for every 10m sold Wii U's - so NSMBU and NL seems like safe bets for entering the top 20 most sold games on a single platform.

Furthermore, I think VGChartz should add a "Like"-button.
