SCEE will show its Sony motion tech at Develop in Brighton this morning, and BG247 will be liveblogging the session after the link.
The firm promises to show "a lot more about the new PS3 controller shown at E3," giving "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."
Missable? Not really. VG247 will be filming it as well, so they'll aim to get video live as soon as they can after it's over.
