Yeah Goshi managed to 'borrow' the PSwii60 that was being presented at E3 2009.
he is one of the very few to have a leaked prototype model, don't worry if they drop the project, you can always buy a prototype from ebay for about a googolplex dollars.

also sony are working on the pray station thlee (rumored to be called PS3.5 outside of japan (search on endlessparadigm's search engine for more info))

and there's also that portable that Somy's working on.
