Though some have doubted the viability of Nintendo's latest console, the Wii U is off to a pretty strong start. The Japanese video game pioneer has announced that it sold over 400,000 units of the new Wii in the week since it launched on November 18. That breaks the record set by the original Wii, which sold 300,000 units in its first week back in 2006.

The original Wii, however, was something of a sleeper hit, growing in popularity over time and continuing to sell out several months after its release. Whether or not the Wii U will be able to repeat that kind of success remains to be seen. Reviews of the console, which is the first in a coming new generation of gaming systems, have so far been mixed.

The Wii U features an innovative touchscreen controller that acts as a second screen for gameplay as well as high definition graphics, a first for Nintendo. In a repeat of the last generation of consoles, competitors Microsoft and Sony are expected to release their own much more powerful systems late next year.
