"3DS shows that the sector is still there and that Nintendo is doing very well in it, so there is a market to harness."

That quote alone is basically saying Nintendo's success in that market means Vita can have success in it as well.

However, Nintendo actually makes an effort in that market. Sony has basically given up and is trying to make other uses for the Vita.

Not saying Sony is putting a lot of effort saving the vita, but that's a compliment for Nintendo too, and he's always looking the things for the dark side.
