The reason i'm cynical about the WiiU is that, simply put, if this is the console expected to carry the next generation, it's going to look pretty poor compared to Microsoft's and Sony's next gen consoles which are estimated to be out some time in 2014. People are saying the WiiU targets 'hardcore' gamers, but honestly, when the status quo has been restored and all three next gen consoles are on the market, it will go back to the way things were - the most powerful machines being Sony and Microsoft and Nintendo with "last gen" hardware / graphical fidelity.
Personally, as someone who enjoys Nintendo games on occasion (i bought a Wii purely for first party software, Mario and friends have been a staple of my gaming life since my induction to the culture) the WiiU holds a lot more appeal than the Wii. This is because i always play sitting down, which can be difficult with motion controls like the Wiimote. With the WiiU's touch pad, i will be able to play sitting down. (i think) This is a step in the right direction for me and instantly holds appeal. The only quibble i have with the pad system is having to look at the screen on the pad. We don't look at our controllers when we play, and having to look down every five seconds will be a real pain. I remember when i let my dad have a go with an xbox controller for the first time, every few seconds he had to look at the buttons to make sure he was pressing the right one and it made the whole experience both painful for him and painful to watch. Now imagine that scenario every time you play a new game. Want to select Link's bow? Look at the screen. Want to select his bombs? Better look at the screen again. I honestly think it would be far more useful to the player to simply press the start button and call up the inventory screen and select it manually with an analogue stick rather than kinetically with a touch screen. Maybe the actual implementation will be less finicky than this, we'll have to wait and see.
The lack of announcements about their (new?) planned online services for the forseeable future is worrying, no-one wants to be messing around with friend codes. They need to put up a system akin to the PSN or Xbox Live if they hope to win back investors and compete in the global market. Lastly, because i am a huge xbox achievement addict, i will be waiting patiently for Microsoft's new console first before making the leap into the next generation. Sony's failures have been enough to dissuade me from buying into anymore of their products, and their exclusives (aside from Metal Gear Solid - which is exclusive no longer) aren't enough to draw me back in, especially compared to Nintendo. So while i may get a WiiU some time in the future, i am in no rush, and it will be after Microsoft's next gen console.
