The platform holder is set to confirm the list at its product showcase in San Francisco later today.
Epic's Gears of War 2 will be introduced at the show first, with MS confirming that today's showcase event will see the studio’s Cliff Bleszinski "demonstrate dramatic new gameplay elements and stunning visual effects in a campaign sequence from early in the game". The title is due for a Holiday (Christmas) release.
