I'm not sure. I just followed the link off their twitter feed, and it brought me to a form. I think you had to fill out the form to get any details.
Ironically enough, Sony started an indy program today. There is a form to fill out on their site. It covers all their consoles.
Hmmm, is this different from the Playstation Suite (Mobile) SDK they released about a year ago? Granted, they haven't done as well as Microsoft in promoting their indie-friendly SDK to developers. I searched for "Sony Indie SDK" on Google and didn't find anything relevant and new from this week.
