I am sure alot of people are waiting for Halo 4 to come out, including myself. I am also sure that alot of people are not playing Reach anymore for more reasons than I can count.
I only suggest that those excited and going to be playing Halo 4 regularly to remain on Reach, and up their gameplay. There are going to be a great number of Tryhards coming out on 4 and I suggest that everyone hone their skills to avoid the inevitable try hards.
