CCP recently trademarked a new title:
Nobody knows what it will be, but historically CCP has only trademarked its game titles, not its expansions, implying that this is a bit more serious. However considering how stretched thin CCP already is, it will have to be something that doesn’t take a lot of developer time.
Perhaps an Eve roleplaying game?
Serpentine's Eve 
It could be something like a RTS. Legion implies you’d be controlling multiple units.
Could be Dust514 for PC
As it turned out, yes.
