I'd say same as the 3DS, well for different reasons obviously. The Vita is not selling anymore and the 3DS is going to be replaced full time by the Switch or at least I suspect that much. I don't see much future in the 3DS because of the Switch I mean.
So will we have soon a chart that has neither 3DS nor Vita? Maybe, in the meantime it does not hurt to have them both there right?
38k vs 3k is a huge margin.
