This year, rumors are swirling around Halo 6, the newest installment in the hit space epic series that helped launch the original Xbox nearly two decades ago. Additionally, the previous installment, Halo 5: Guardians, came out three years ago, and that installment was three years after Halo 4. So, it's safe to assume we'll hear something Halo related.

There's also interest in a new installment in the futuristic action series, Gears of War. These rumors are based on an unconfirmed leak from Walmart, but many fans now have their hopes up. Even Cliff Bleszinski, who designed the original Gears of War and worked on some of the sequels before leaving to help found a new game studio, has said he's hoping to see something.
