Something relevant that I replied to in the news post and thought I'd post here as well:
If anyone doesn't have an Xbox controller to use with their PC and is worried that this might be a problem, then as long as you have a Playstation controller (and if you're here you probably do) you should be fine*.
Google ScpToolkit. It's a program to make your computer treat your DS3 or DS4 as an Xbox controller. You'll find a bunch of reddit posts, emulator forum posts and github references that should get you all the information you need. It was plug and play for me, but it's possible depending on your config that you may need to tinker a little. I've been using it to play games with a DS3 for some time and it works great.
The other option is MotionInJoy, which also works fine, but I found to be a little more temperamental for me. I haven't used it in about a year, as I kept needing to reload it to get the drivers to work. YMMV.
*Or if you just like Playstation controllers better.
