There's seems to be an assumption around here that Wii U owner's game-purchasing habits exist in a vacuum. That the likelihood of a Wii U owner purchasing a particular multi-plat is not affected by the availability of the game on another platforms that one might own or the cost of a particular game on another system.
For example I did not purchase FIFA 13 on the Wii U because it was inferior to the other versions, and cost more at release. I have the option of purchasing it on the PC or Xbox 360 and if I get it I will get one of the other versions. Given parity though I would prefer to get it on the Wii U as that is my primary system for gaming but I'm not going to pay for what I know to be a bad deal particularly when I have other options.
If I only owned a Wii U, would I have bought the game then, I honestly don't know. Now we can all make claims regarding what games we might have bought if certain criteria were met but I'm curious how many other Wii U owners actually have other options in terms of purchasing multiplatform games.
As a Wii U owner do you have another non-Nintendo plaform? Sub-question: Did the the earlier availability, cheaper cost or superiority of a multi-platform game prevent you from buying said game on the Wii U? (which game/s?)
Edit: I clearly should have added the option of 'WiiU only" to the poll. Can you edit polls without losing the exisiting votes?
