According to the official programme
for this year's Develop Conference (a UK soiree for game devs), the recently totally confirmed
PlayStation Motion Controller will be a highlight of a keynote titled "PlayStation: Cutting Edge Technologies." Specifically, attendees are being told to "expect to hear a lot more about the new PS3 controller shown at E3, together with vision processing and advanced graphics techniques in the PS3 libraries" during a presentation by SCEE staff.
The keynote description also makes mention of "several real-world examples of such techniques as used in recent and soon to be released PS3 and PSP titles from both Sony Computer Entertainment first party and external developers," but don't take that to mean "OMG actual games using motion control;" it's referring to the aforementioned "adavanced graphics techniques," which should still be pretty ... and
pretty ace. The conference runs July 14 through 16 in Brighton.
