Entirely? Probably not. Right now is probably the closest I've ever come from dipping out on consoles entirely, but I still own a PS4 and Wii U, though very little chance I get an Xbone now that Windows 10 cross-play is a thing. I rarely play my PS4 though; it's gotten some love lately because of FF XV, and my Wii U has been collecting dust besides a spur of the moment Pokken session I had a couple months ago.
I've now got almost every game I've ever wanted on my PC in some form or another, have the ability to connect a wide range of console and other controllers to it (360, Wii, PS4, Steam Controller, 8bitdo SNES Controller, etc.), and it's hooked up to my living room TV if I ever want to game on the couch or have friends over. It's great, I love it, but I don't see everything coming to it anytime soon and since I just love to play games over anything else, I'll probably still own consoles.
