The first sentence is clear enough, but the second one comes off as somewhat squishier. It's almost certainly just the usual corporate-speak boilerplate—and yet Steam continues to list the game as launching in "Early 2015," despite January 27 being just 18 days away. The system requirements haven't been released yet, either. For a game we're meant to be playing in less than three weeks, that seems a little odd.
Which isn't to suggest that shenanigans are afoot: Rockstar has never been the most vocal studio in the world, and so while this might seem unusual, it's not terribly strange by the firm's standards. So January 27 it is—and we'll of course let you know if and when we hear different.
