It's supposed to have better graphics (full 1080p), and be more powerful than the PlayStation 3 and the XBox 360. Hopefully it will be on par with the upcoming PlayStation 4 and the Xbox 720, or Nintendo will just be playing catch up.

I'm seeing some pretty good titles on the list of games scheduled to be released, so far.
I like that they are working a lot more with 3rd party developers, and targeting the more serious, hardcore gamers now.
The graphics look pretty sick!
»
en.wikipedia.org/wiki/List_of_Wii_U_gamesGames that I saw on that list that look like they are for more serious gamers include:
New Super Mario Bros U
Aliens: Colonial Marines
Ninja Gaiden 3: Razor's Edge
Darksiders II
Assassin's Creed III
Batman: Arkham City Armored Edition
Mass Effect 3
Tekken Tag Tournament 2
ZombiU
Untitled Battlefield
Call of Duty: Black Ops II
Tom Clancy's Ghost Recon Online
Injustice: Gods Among Us
Sacrilegium
Untitled The Legend of Zelda
I'm sure much more games for serious gamers will join that list as the release date gets closer.

en.wikipedia.org/wiki/Wii_USome quick highlights from the article:
Wii U GamePad 
Wii U GamePad (White)
Main article: Wii U GamePad
The Wii U GamePad is the main controller for the Wii U. It features a built-in touchscreen, which can either supplement or replicate the gameplay shown on the main display, and can function as a standalone screen without the use of a television screen. The controller features an accelerometer, gyroscope, camera, dual analog sticks, a built-in microphone, and supports near field communication (which can be used for, among other uses, figurines that can interact with the console and wireless credit card payments with compatible cards). The console will also be compatible with the Wii Remote Plus, Wii Nunchuk and Wii Balance Board, as well as a Wii U Pro Controller for more traditional controls. Two GamePads are supported per console.
Shigeru Miyamoto promoted the idea of the GamePad, stating that he supports being able to use a secondary screen while someone else is watching the television. Wii U is said to offer asymmetric competition, where the player using the GamePad has one experience and wins in a certain way, while competing players have different ways to play and win.
Wii U Pro Controller 
Wii U Pro Controller (black and white)
The Wii U Pro Controller is the second controller released for the console, available separately. Like more traditional controllers, it features standard control sticks, buttons, and triggers. Nintendo unveiled the Pro Controller at E3 2012 with the aim of attracting more "hardcore" gamers to make the Wii U more competitive with Sony's and Microsoft's offering. Many video game journalists have noted the similarity between the controller and Microsoft's Xbox 360 Controller; However, Nintendo claims that the design of the Pro Controller is an enhanced version of the Wii Classic controller and "offers a richer experience."
Technical specificationsNintendo has released technical specifications of the Wii U hardware, which are listed below. These specifications are subject to change.
ProcessorsCPU: IBM POWER7-based multi-core processor.
GPU: Custom AMD Radeon High Definition GPU
The Wii U CPU is designed by IBM. It is described by IBM as an "all-new, POWER-based microprocessor",[66] the processor is a multi-core design manufactured at 45 nm with an eDRAM cache. Although neither Nintendo nor IBM has revealed detailed specifications, such as the number of cores,clock rate, or cache sizes, references to the chip containing "a lot" of eDRAM and "the same processor technology found in Watson" indicate that the processor shares some characteristics with IBM's POWER7 processor, which powers the Watson computer system and incorporates a large L3 eDRAM cache. The Wii U CPU will be produced by IBM at their 300 mm semiconductor manufacturing facility in East Fishkill, New York.

Media CapabilitiesNintendo is working with Netflix, Hulu Plus, Amazon Instant Video, and YouTube to bring streaming digital movie and television content to the Wii U. Nintendo has demonstrated that simple gestures can be used on the Wii U GamePad to transfer video content from the GamePad to the television screen. Users will also have the ability to switch from the television screen to the Wii U GamePad when watching videos.
The Wii U GamePad can also be used as a universal television remote with a built in guide, even when the Wii U is off. This will allow users to use the Wii U GamePad as a means to switch television inputs, browse through channels, look through channel programming guides, and turn the Wii U console on.
