Don't know about the others, but WiiMusic definitely shouldn't be on that list. It will crack 1m sales this week, and is just outside the top#10 for best weekly sellers last week - at around 200k/week. Its definitely not a "causality" (otherwise the industry is doing a LOT better than I thought :P).
Same goes for LBP, although Sony would have been hoping for more by now - maybe double.
