What will the final 3DS-to-Vita lifetime sales gap be?

[Jizz_Beard_thePirate]

50-60 million cause the n3ds + 3ds should sell 10 million this year which will bring it to 60 million and the NX (which will most likely be a handheld) will be announced in 2016 should lower its sales at e3 an it will die off eventually. And of course, the vita is basically dead and will continue to die as exclusives and games like Gravity Rush (rumored) gets to be on the ps4
