FFS! Even Valve are getting in on the "zero content" announcement of future announcements!
Worse than that, this is almost certainly an announcement about future announcements about future projects, which tend to have a lifecycle of several years (give or take Valve Time).
Valve aren't even a public company, so this kind of announcement achieves nothing, not even artificially inflating the share price.
