Once again there's no surprises in this week's multi-format videogames chart with GTA IV retaining top position and Wii Fit nestled snugly in at number 2.

Games on Nintendo's format are dominating though with 20 titles out of the top 40 being on either the Wii or DS. New Mario Kart Wii stock has arrived and strong sales has seen the game shoot up from 9th position into 3rd.
