Has anyone else completely lost interest in this game? :/
It's going to be the same deal with me as what happened with GTA IV. Did not purchase on any other platform, waited for PC release, gave up waiting, forgot about it then eventually bought it a year or 2 after launch for 70/80% off.
I haven't so much lost interest as pushed it to the back of my mind and left it there. That's what I do with any game that ends up being delayed or is more than a month or so from release. It keeps me from being too impatient for it. It also lets me get to a bit of an "eh, it'll release when it releases, oh well" state without ceasing to care about it entirely.
