Portable Nintendo Wii that runs on batteries: will it be any good?

Here we have a little sneak look at the upcoming Portable Nintendo Wii that is supposed to be coming to Japan sometime this year. However I was surprised to hear that the world’s fastest selling console will run on batteries.

I would like to ask people a question, why would anybody want a portable Nintendo Wii. The thing looks as if it has been put together by an 8-year-old. Looks like Nintendo have lost the plot a little with this one.
