I'm not sure if this is a weird PR tactic to raise awareness of S.T.A.L.K.E.R. 2, a way to attract potential funders or something else entirely, but it's worth noting that the official S.T.A.L.K.E.R. twitter account tweeted about an animation reel video from S.T.A.L.K.E.R. 2.
Whatever it means, we hope that the project gets released eventually.
