Several of the PS2Dev guys are also part of the resident PS3 Dev team here, so they are all "in the loop" regarding what has been tried and what needs attention, etc.
As mentioned in our recent Site News, there is a joint project that has been in the works for some time now, and very soon it will be made public so the community can help the Devs out as well.
Aside from that, several others are actively involved in side-projects (PS3 related) of their own so these will also tie into the larger picture as each shares news of their work publically.
PS: Last night CJPC showed me a really
cool screenshot of something he's been working on via the Debug... I'm sure he'll post it soon enough (when he's ready)
