It will fit for sure... It would be a bit stupid of Nintendo if they bundled a console that doesn't have enough space to fit the free game that people paid for in order to get the bundle in the first place...
Would be the biggest troll ever and it would benefit the external hard drive companies more than it would benefit Nintendo which would be even more weird
