5 new PSP colors were shown off at TGS this week, although they were not shown as shipping units just demos. Sony revealed the PSP sporting bright yellow, metallic red, metallic blue, and 2 camouflage variations. Personally, I think that all of these new colours are appalling and am not interested in any of them should they ever ship. Lets hope that Sony thinks this out before flooding the market with alternate coloured units. Nintendo can get away with it because the GB, GBA and DS are nearly throw-away cheap.
