Charts: GTA IV and Wii Fit unstoppable News

Grand Theft Auto IV and Wii Fit have spent a third week at the top of the UK all-formats chart.

Both dropped nearly 50 percent in sales, but still had enough in the tank to see off Mario Kart Wii - which boosted from nine to three.

Then, inevitably, came the pounding feet of Mario & Sonic at the Olympic Games at four, followed by Wii Play at five.

Pro Evolution Soccer 2008 gained half-a-yard to make six, out-flanking consistent best sellers Call of Duty 4 at eight and Brain Training at nine.

Guitar Hero III managed to finish with a flourish to climb from 11 and round the chart off at 10.

Meanwhile, two week-old Boom Blox managed to finally make the list at 21, despite critical acclaim and being a big name collaboration with Steven Spielberg.

Two other fortnight-old titles managed to break into the Top 40 as well: High School Musical: Work This Out at 14, and Speed Racer at 37.

Top Trumps: Doctor Who was the only new entry at 22.
