From what I understood in the COD MW4 news, only the second phase will be open to players who don't own the game, but the first phase will only be available to those who have purchased the game? XD

The logic should be a bit more like: alpha testing to gather feedback from the entire community, improve it, and then offer the option to purchase the final game with the community's improvements, I don't know, that's what I think.

The trailer for The Witcher DLC looks pretty good. Damn, the PS6 news, they haven't even released the fifth one and they already want to release the sixth xD
