Last official word we had on the launch of Sony's PS3 Motion Controller was Spring 2010. However, we just received a press release from Sony Japan with a revised availability of "Fall 2010." The calendar push affects Japan, Asia, North America, and Europe. In the statement, Kaz Hirai avoids using the "d" word saying only:
"We have decided to release the Motion Controller in fall 2010 when we will be able to offer an exciting and varied line-up of software titles that will deliver the new entertainment experience to PS3 users."
Still no mention of Arc though Sony does concede that "Motion Controller" is just a tentative name. Full press release after the break.
