Developers of video games were completely not aware of Nintendo Wii MotionPlus peripheral that improves precision of Wiimote game controller. This may slowdown the adoption of the new controller by video games set to emerge in the coming year, which lowers advantages of the system for end-users.

The Wii MotionPlus is plugged to the bottom of Wiimote controller and, combined with the accelerometer and the sensor bar, allows for more comprehensive tracking of a player’s arm position and orientation.

Apparently, Nintendo has not notified any of third-party game developers polled by Eurogamer web-site about the development of Wii MotionPlus accessory, which means that games that take advantage of the device are six to nine months away. This indicates that at least initially the MotionPlus add-on will hardly become popular among customers, who do not buy Wii Sports: Resort title, which is set to bundle the new device.

Nintendo did not comment on the news-story.

Nintendo Wii features IBM’s custom PowerPC architecture-based microprocessor named Broadway clocked at 729MHz and code-named Hollywood chip with built-in graphics core, DSP and I/O features from ATI that operates at 243MHz, earlier reports suggested. Nintendo Wii uses 91MB of memory in total: 23MB of “main” 1T-SRAM, 64MB of “external” 1T-SRAM and 3MB texture buffer on the GPU. Nintendo’s Wii does not feature a hard disk drive, instead, it boasts with 512MB of flash memory, but the console will also have a card reader, which will allow installing more memory.

Nintendo set the recommended retail price of ¥25 000 (about $204) in Japan, $249 in the U.S. and €249 ($342) in Europe.
