I think it'll likely fall short, but may do it in early Dec.

I'm not sure but by the end of the year, it should hit 3 million.

It'll likely do it if the game is heavily bundled in the christmas period.

I say it could reach that

Maybe, but I think it will most likely during the holiday season.. Either way, 3D World deserves to sell as much as possible because it's a great game...

Probably. Is it still bundled with the console somewhere?

I think the consensus agrees that this game will hit it by the end of the year. I certainly believe so.

January 2015. 

Yes, easily, it'll start to really sell very well around november through december. Who knows, it might hit 4 million by year's end.

Its never been properly bundled, i think it may have had some sort of limited edition Mario bundle in the UK,but i reckon over 90% of sales are unbundled.
