Both GameStop and Amazon currently have listings for Gears of War 2: Game of the Year Edition, and while the prices might be slightly different ($39.99 at GameStop, $36.99 at Amazon), both seem to agree on the release date: September 1st.
In addition to the retail game, the GOTY Edition includes the All Fronts Collection DLC, which consists of the Dark Corners DLC, plus the Flashback, Combustible, and Snowblind map packs. The DLC alone is $20, so this is edition is great deal for anyone who hasn’t picked up Gears 2 yet.
I’m waiting to hear back from Epic for confirmation on all of this, so I’ll let you know if there are any discrepancies.
Update: Confirmed! September 1st it is.
