Prediction League 2013 - Entire Year
Predict how much these items will sell in the entire year of 2013:
[3DS] Hardware - 10M
[WIU] Hardware - 2.2M
[3DS] Pokemon X/Y - 6M
[3DS] Monster Hunter 4 - 5.5M
[3DS] Animal Crossing: New Leaf - 1.6M
[3DS] Dragon Quest VII - 2.1M
[3DS] New Super Mario Bros. 2 - 0.8M
[WIU] New Super Mario Bros. U - 1.4M
[WIU] Nintendo Land - 0.35M
10M for 3DS? 2.2M for WiiU?
You do realise that NDS record was 7M! and 2.2M was the PSP YTD for 2010 (e.g. its unlikely that WiiU will unlikely do a number like that even with a turnaround - which would come after the price drop in summer time!)
