It would be nice to see this kept up to date. I'd like to see how many Nintendo game releases it takes to get the Wii U up to the Gamecube.
I had a look, and these seem to be the numbers:
April - 38,000 Diff - 43,935
May - 36,000 Diff - 75,063
June - 42,000 Diff - 171,100
So the Wii U is behind the Gamecube by 701,491 in NA right now.
