Within the next few months, Wii Sports will be the best selling game ever

[Zucas]

Yes it will become the best selling game.

Now for other comparisons I like to compare the best selling game void of multi game and bundled games. And in this case, a Wii game is once again about to take the crown:

1. GTA: San Andreas PS2- 17.50
2. Wii Play- 17.03
3. New Super Mario Bros.- 16.55

So actually its two things about to get dethroned. The actual best selling game ever and then the "other" best selling game ever. And its even got a friend ready to put GTA in 3rd place haha.
