RSV2 PS3 is still ahead of RSV2 360, just because it dropped more places doesn't mean it dropped more units. Besides, if it was a mistake last week that would mean this week RSV2 360 totally collapsed, and RS2 PS3 didn't drop any places at all. That makes no sense. Logically it cannot be a mistake.

Not sure at all, do you remember what happened to army of two in France?

Week 10

3.NEW SUPER MARIO BROS. (Nintendo) NDS (+1)
4.ARMY OF TWO (Electronic Arts) 360 (E)
5.Wii PLAY (Nintendo) Wii (-3)
6.ARMY OF TWO (Electronic Arts) PS3 (E)

Week 11

8.ARMY OF TWO (Electronic Arts) PS3 (-2)
9.PRO EVOLUTION SOCCER 2008 (Konami) PSP (-1)
10.MARIO KART DS (Nintendo) NDS (+2)
11.LEA: PASSION BEBE (Ubisoft) NDS (-)
12.PROGRAMME D'ENTRAINEMENT CEREBRAL AVANCE (Nintendo) NDS (+1)
13.CALL OF DUTY 4: MODERN WARFARE (Activision) PS3 (+2)
14.ARMY OF TWO (Electronic Arts) 360 (-10)

For me, no reasons, it was not the same story for rainbow six vegas 2.

The tv channel which give the top 20 had already make a mistake before for Assassin's creed in his second week, she could really have done the same mistake in week 12 for rsv2.

If there is the mistake, it give that:

Week 12:

6.RAINBOW SIX VEGAS 2 (Ubisoft) 360 (E)
7.LEA: PASSION BEBE (Ubisoft) NDS (+4)
8.PROGRAMME D'ENTRAINEMENT CEREBRAL DU Dr. KAWASHIMA (Nintendo) NDS (-1)
9.MARIO PARTY DS (Nintendo) NDS (-3)
10.MARIO KART DS (Nintendo) NDS (-)
11.RAINBOW SIX VEGAS 2 (Ubisoft) PS3 (E)

Week 13:

11.RAINBOW SIX VEGAS 2 (Ubisoft) PS3 (-)
12.PROGRAMME D'ENTRAINEMENT CEREBRAL AVANCE (Nintendo) NDS (-)
13.GOD OF WAR: CHAINS OF OLYMPUS (Sony) PSP(E)
14.RAINBOW SIX VEGAS 2 (Ubisoft) 360 (-8)

For me this version is more logical in comparison with what happend to army of two, or others games before.

Turns out GT5:P debut week in UK was 108k. RSV2 on 360 sold 149k in UK weeks 12 + 13.

Switzerland weeks 1 - 13
