Looking ahead at the upcoming release schedule it’s becoming hard to guess exactly what is going to usurp Nintendo’s Wii Fit from the top of the ELSPA GfK-ChartTrack All Formats Top 40, with the title now enjoying its sixth successive week at the top.

It's the 15th time Wii Fit has topped the UK listings – if it can manage another three victories it will topple Eidos' Who Wants To Be A Millionaire as the most successful chart topper ever.

There’s no change, either, in the next three games with Activision Blizzard’s X-Men Origins: Wolverine, EA’s FIFA 09 and Nintendo’s Wii Play holding firm.

Sega’s Mario and Sonic at the Olympic Games re-enters the Top Ten after a brief holiday, claiming ninth spot. Just behind it is the only Top Ten debutant – Nintendo’s Rhythm Paradise.

The only other new entry this week is Disney Interactive’s Hannah Montana: The Movie in 18th, whilst the lower reaches of the listings see Eidos’ Tomb Raider: Underworld and EA’s Burnout Paradise re-enter in 38th and 40th respectively.
