Innerbits.com, a blog run by "a few guys working in the games industry" who "want to address rumors, and a give a voice to game developers who would be otherwise afraid to speak up," claims that rumbling SIXAXIS controllers are now in the hands of a select few developers. The information on these prototype controllers is still kept very tight to Sony's chest. Apparently the details will be revealed over the next two or three months, with Leipzig the obvious venue of choice. We'll be there to let you know if that's the case.
Innerbits also reports that controllers bundled with consoles are quietly being swapped out with newer versions. Nothing too exciting, just improved motion sensing. We're reminded that hardware updates occur all the time without us being told. Remember the removal of the Emotion Engine?
Finally, we're told not to get too excited about the patent for PSP/Dual Analogue controller connectivity. Companies patent hundreds of things that never see the light of day. We're going to remain hopeful, but not hold our breath.
