Rock Band 4 not coming to Wii U because "the audience is not there"

[Iyasu]

I wonder how many people here, that are complaining about Rock Band 4 not coming to Wii U (for the time being), are complaining because the Wii U is being left out again, or because they want to buy Rock Band 4 on the Wii U?

(Not saying there aren't people who really want the game on Wii U)

I'm asking because I'm in the camp of people who dislike it, when 3rd's skip the Wii U (or release inferior late ports and expect full price), but probably wouldn't buy Rock Band 4 for the Wii U, as I'm not interested in it.

Harmonix reasoning seems legitimate to me, the risk on the other platforms is probably lower.
Harmonix isn't a huge publisher who can take a big flop, so they have to play it safe.
