Uncharted PSP? Yes Please, Sir!

Ben Weston - currently a programmer at Rebellion in the UK - notes that during his time at Naughty Dog he worked on an "Action Game" for the PSP alongside Uncharted: Drake's Fortune. It's probably safe to assume the project has been halted and/or scrapped by now - but it's interesting that this information has emerged.

Was Uncharted PSP in development at one stage? We'll probably never know.
