Agreed. Like I said earlier, I was the first person at our local store to ask about the Wii U and it was well after noon (right around 2 PM, in fact). I wouldn't be surprised if I could go back right now and order another one. There definitely is some demand for the console, but I don't think it will be anything like the first Wii.
The thing is too, the WiiU is launching in a very different world-- everyone's bowled using motion controls now, the Wii is in pretty much every home that REALLY wants one, the economy's been in the toilet for 4 years, etc, etc.
I'm sure there's demand for this-- it's the first new home console launch in a long time. But honestly the launch lineup isn't THAT fantastic (at least IMHO), the console costs $50-$100 more than the Wii did at launch, the new functionality is a bit harder to really get excited about (Motion control in 2006 was just MINDBLOWING! Playing a game on a tablet.. not so much )
I'm sure it will be initially tough to get. Maybe even though Christmas. And I am sure Nintendo will do everything in their power to remind everyone of the craziness of the Wii launch and try to control the resupplies so that they're "moderately difficult but not impossible" to get one if you didn't pre-order. Enough to build hype, not enough to lose sales. This Christmas is CRITICAL for Nintendo to get a lead in "next next gen" before Sony and Microsoft start working to steal their thunder.
I hate to admit it but I sort of pre-ordered on the hype. There's not a whole lot I want to play RIGHT NOW (well, at launch) but this is my hobby and I enjoy it, and I'm sure it'll be a fun system.
(I will say-- I think people forget what a surprise the Wii was. I remember a LOT of people expecting it to bomb. Remember it launched 2 days after the PS3 and people thought the PS3 would steal all of Nintendo's thunder... but then it became apparent that weekend that while the PS3 was selling well, a lot more people wanted the Wii.. the hype about the Wii being impossible to buy sort of came up 'overnight' as the launch happened and suddenly everyone was out of stock. I think before that everyone had sort of low key expectations about the Wii and expected the PS3 to be massive)
