I also hope that there will be a Wii U version.... but I won't buy it.
I love my Wii U, but I also want to play the best possible version of Project Ukulele.
Looking at the two screenshots from the presentation,
I already can assume that they'll have to downgrade the Wii U version.
And If I have the choice to play the game on Steam with 60 fps, Anti Aliasing and any resolution my hardware can handle (I'll go 4K this year)
OR playing a Wii U version without Anti Aliasing, perhaps only in 720p and/or maybe just 30 frames, I chose the PC.
The Wii U is my favorite console because of those great Nintendo games.
But when we talk about multi platform games: no chance in hell.
At least until Nintendo decides to once again sell hardware that isn't 7 years old at the first release day.
BigN is so afraid of casual gamers to not be willing to pay more than 299€/$ that they don't realise/care about how the non-casual gamers may suffer under the limitations that the outdated hardware is forcing on the available games.
I rather wait a few months and save up 400-600 bucks than being able to afford a new console on day one but receiving hardware that is older than my sticky & yellow microwave.
Good things have a price, and 400-600 bucks isn't that much for some decent/current gaming hardware. Building a PC with similar output is much more expensive.
(I don't wan't to say 400-600 $/€ wouldn't be much money, but assuming you aren't a student with allowance money anymore, it's just a matter of being patient a few weeks.)
Nintendo's blue ocean strategy (winning new customer groups that weren't gamers before --> parents, elderly people) was a huge success on the Wii.
But it was in the nature of this matter that those new customers said "Why should I get a Wii U? I already have a Nintendo."
And the old customers miss the times of N64 and Gamecube when owning a Nintendo console actually meant having a current gen console that is not missing out on multi platform games and is not receiving inferior/downgraded ports of what everyone else is playing.
So while some people like to see the bad sales numbers of the Wii U as a sign that Nintendo might leave the hardware market, I see the opportunity that they'll finally enter it again with an serious approach that has the core gamers more in mind than the Wii Fit moms.
I apologise if anyone should feel offended or have the impression that I went off-topic to far.
