wii fans get ready to chuck your nunchucks. a new system with a tablet-sized controller is in the works -- it's called the wii-u. >> it functions like a traditional controller but it also has a 6.2-inch screen built right inside of it. >> reporter: outside gaming nintendo says it can serve as a secondary web browser, video chat tool, even acting as a scale so gamers can weigh themselves. >> it will be backward compatible with wii games and certainly wii input devices. >> reporter: nintendo hasn't said how much it will charge for the wii-u. and you will have to wait a wee bit longer before one lands in your living room. nintendo's launch date simply some time after april of next year. >> whoo! rob hayes reporting for abc news. >> you can hardly contain your enthusiasm. for all this. >> that was a lot of enthusiasm. >> did you see the people coming in, dude, dude, dude -- if you are a single woman looking to meet someone, that's where you should go. >> with nintendo stuff it looks silly in the beginning but ends up being pretty cool.
