Bungie’s Halo 3 ranks a most-promising second. The has yet to be released (it will hit the shops on September 25), but given it’s number of pre-orders chances are that it just might turn up as the top-selling game for all formats even before the actual release.

All in all, it’s been a really good for Microsoft’s Xbox 360, who now holds both top stops in its grasp. The Wii only managed to get hold of the third position (Metroid Prime 3: Corruption), followed by 2 DS titles.

One PC title managed to be part of the top 10 club. As everyone expected, it was BioShock.

The complete top is listed down below:

1. BioShock – 2K Games (Xbox 360)
2. Halo 3 – Microsoft (Xbox 360)
3. Metroid Prime 3: Corruption – Nintendo (Wii)
4. Brain Age 2: More Training in Minutes a Day – Nintendo (DS)
