I'd be surprised. The PS3's keys were leaked too (by the same group, in fact), and Sony managed to put the genie back in the bottle in a pretty amazing way.
This was because the ps3 had a very strong processor made by ibm, using rhe powerpc isa.
This meant that ibm started losing sales of their powerpc systems.
So the story i know is that ibm "asked" sony to stop allowing linux on the ps3.
That new firmware lasted for more than a year, too.
