I think Stitch is making a generalization of games that are selling very well on DS (mainly due to the massive installbase) and then much smaller sales on the Wii (due to a much smaller instalbase), and saying Pokemon as one obvious example.
Arguments comparing gameplay are really irrelevant as I think the point is about market size. Another example is Cooking Mama: decent sales on the DS but very low on the Wii. The games are pretty much similar. The difference in sales is coming from the differential in DS vs Wii market size.
However, given the current forecast for lifetime sales of the Wii, the differential between the two will narrow if you believe the nearly 80 million unit Wii prediction.
