The notion of "Freelancer 2" has done the rounds every 6 months or so, for as long as I can remember. There actually was a "Freelancer 2" (aka. Project Lonestar) for the Xbox some years ago, but by all accounts it was just a reskinning of FL and a complete dogs breakfast. So don't bother googling it
Over the years there have also been abortive attempts by the fan community to obtain the source code from Micro$oft, who has in turn told everyone to "get stuffed" despite showing zero interest in an ongoing FL franchise, much to no one's surprise.
As other people have commented there are currently a couple of projects to reinvent FL in Unity, which look very promising, and probably a far better idea than trying to work the huge pile of spaghetti called "Microsoft code". Unfortunately unless the devs introduce something entirely new to the gameplay and/or universe, they'll be branded "FL clones" and only really of interest to hardcore fans. (Me included)
Oh and don't even bother mentioning that vaporware Star Citizen.
tl;dr: Don't hold your breath. Although Discovery is so damn huge it could almost be considered FL2.
