People love to state opinions as facts, many news shows make careers out of it. The fact is if we do look at this scientifically I think we would see that the individual Vita launch games likey did better than Switch launch games minus Zelda. On that same page though I can say with extreme confidence that no Vita game had more than a 100% attach rate. It's comparing apples to apples, just different kinds of apples.
I don't think so.
