This months N-Gamer magazine has revealed some new information in regards to the Wii's controller and sensor bar.
The Wiimote is to take 2 AA batteries and turn them into 60 hours of gameplay. Should the player be using the sensor bar, however, then the time is cut in half to 30 hours.
Also, the 6kb of internal memory confirmed to be included in the Wiimote is going to be used to "personalize your remote," which we assume is code for "store profile settings."
As for the sensor bar, the magazine states that the previous version that was seen at E3 has been made smaller. The magazine compares the size to that of a "couple of pencils glued together."
They also speak some on the use of SD cards, reiterating that they will be used to house Virtual Console titles. The problem is that you may not play them on another Wii. They refer to this as "Digital Rights Management."
