They are more interested in getting the actual games but its kind hard when you have multiplat titles that sell better on competitor systems along with the fact that some of the ports are gimped like Mass Effect 3 being sold for $59.99 along the same time as Mass Effect Trilogy which again was the same price.
Which would you buy? Mass Effect 3 on WiiU for $59.99 or the entire Trilogy on PC/Xbox360/PS3 for the same price?

The interest isnt there, yes the first party titles from Nintendo will help but the fact that there hasnt been any notable releases as of yet except for say Pikmin 3 (in Japan) - the sales wont be as much as say the 3DS or the PS3 which keeps on getting content which are usually exclusive or third party multiplats (which again is due to the fact of its userbase).

As for the Vita, a lot of the games are enhanced ports/remakes which imo arent as bad as gimped ports that the WiiU is getting but the demand isnt there because people want exclusives and AAA titles.  Along with the fact when you sell your biggest memory card for $99.99 - it turns off a lot of people (including me which is the main reason why I dont have one yet) - they'll be like why should I buy a game system that will have its biggest memory card for half of the price of its competitor. Yes you can get smaller memory cards and deal with that, but people look at the smallest things - it is what makes us consumers.

Edit: Also doesnt help that one region already has a price cut - some people do research and when they find out in their region the games sell for higher prices - they'll just wait for a price drop and/or sale.

Note I am getting both systems eventually in the future as there are games on both systems that have come out and will be coming out that I am interested in.

I dont care about only AAA titles - I play anything and everything from AAA titles, niche titles, and indie titles.
