Epic has been pimping coverage of Gears of War 3 that will be appearing in the US Official Xbox Mag. Getting the jump on the mag's probable exclusive, the company has outed dedicated servers."We’re bringing dedicated servers to 
Gears of War 3 to drive a balanced, optimized, and thrilling online experience for Gearheads everywhere. For the full scoop on Gears 3’s dedicated servers, new match types, and more..." says the 
posting.
According to 
Shacknews, there will also be a Multiplayer Beta next year.
Apparently we can also expect a further 'litany of revelations" regarding the game, which has been delayed until later next year.
