Dark Souls has managed to make a pretty big name for itself recently, and I think the developers behind it, From Software, have done an incredible job to offer a really unique RPG experience. I've yet to complete the game, but I've enjoyed the game a lot since I first got my hands on it.
I'm sure this is the case for many players, so I can imagine it's sparked a lot of curiosity between those that haven't yet played it. If you sold your PS3 or Xbox 360 to get a brand new console from either Microsoft or Sony, than you probably know what I'm talking about here.
Luckily though, it could be very possible that a Dark Souls 2 port for both the PlayStation 4 and the Xbox One could happen. When asked about a possible cross-gen port by Edge, From Software director Yui Tanimura replied with, "We have not put any thought into this yet, So I unfortunately can't answer at this point."
Whilst this means that From Software haven't already started a PS4 and Xbox One port, it also hasn't ruled out the possibility of it happening in the future. Dark Souls 2 has already been incredibly popular for seventh gen consoles, so I'm sure a port to Xbox One and PlayStation 4 would be appreciated by many fans of the franchise.
Whilst From Software are currently developing Bloodborne, it's not out of the question to hope that a Dark Souls 2 port could also be worked on.
