Confirmation, if required, that the DS is the king of handheld gaming. Chart Track data shows that more than 2 million DS units have been sold in the UK, helped by the likes of Brain Training and Nintendogs which have sold over a million copies each in Europe. Perhaps even more interesting is the confirmation that the DS is outselling the PSP by more than 2.5 to 1. Some developers have expressed concerns about the state of the PSP - particularly low software sales - but I've got a feeling the PS3 launch will see a revival for Sony's seemingly unloved handheld.
