When will the PS4 Beat the PSVita in Japan?

[OneKartVita]

I said 2018. The vita is still selling healthily in japan and could potentially for another 3 years or so. Maybe even longer if it keeps getting ports of PS4 and maybe even NX games.

Unless it tanks next year which I don't think it will, PS4 won't pass it easy. Vita putting up a fight!
