PS Vita vs. Wii U

Between yesterday and today we saw the announcement of the new consoles of two of the biggest companies in the gamig industry, the PS Vita and the Wii U, both of them look pretty awesome and revolutionary thanks to their cool new features:
PS Vita: it has two joysticks incorporated in the handheld, also with the new touch screen that is promising to change the handheld gaming for ever (they said). The handheld will also come with some cool specifications such as a full HD screen and the 3G network, he handheld will be available in winter if it doesn't gets delay and it will have a price of 240$ for the wifi only and a 299$ version for the wifi plus 3G version.
Wii U: he new Nintendo console will feature full HD graphics, a new controller and a new kind of gameplay, the controller is a tablet looking thing with a touch screen, two joysticks an arrow pad and your usual command buttons (A, Y, X, B), the special thing the controller will have is the option to use it like a handheld device, for example if you are playing Mario or Zelda and your dad wants to watch football you van continue your game directly from your wireless controller. We still don't have a price for this awesome looking console but at least we have a release time that would be in 2012 probably spring or summer, we are guessing the price of the Wii U to be around 350$ to even 450$, we hope our first guess is right.
OH!! and before we forget about it, between this two consoles which one would you take and why??
