In a recent interview with the Russian PSP firmware hacking group M33, they were asked the following question and gave the following reply:
PSPX: Are you going to work with other consoles?
M33: Maybe with PS3, we're not interested in other consoles ...
So at least now we know of at least one group interested in the PS3.
Lets hope more will follow.
