Well not necessarily his idea, but the fact that Nintendo is only presenting this solution to remove the barrier people have with buying games. Whereas before you needed to clean the fridge, now you do not. This solves the "storage problem" but doesn't bother with what people were actually complaining about which is the usage problem.
Great, I can download games to my SD card, but why in the hell can't I play them from there too?
The Wii memory should more or less just be augmented by the SD card memory, not treated as two separate things.
