Valve's Steam Page Lists 2 'Upcoming' Games

I've seen people point this out before, but if you go onto Valve's Steam page, and look under 'Upcoming Releases', of course Deadlock is there, but it lists there as being 2 upcoming games, with the other not showing up. I'd also like to point out that while there are also two games set as 'Action, there is only one game under multiplayer, that being Deadlock. So... single player game?
