This is starting to sound a lot like a PC gaming vs Console gaming discussion. They both have their pros and cons, but they're not dramatically different from one other. The big difference being the input source. Keyboard/mouse and a controller.
In theory they'll have the button reassignment and sensitivity adjustments like we do now, and that should be more than enough to allow for comparable results. Most of the other functions are timing and practice, and any player can pick those up over time.
Really we'll just have to wait and see how it turns out. You can actually toss your controller in right now and give it a whirl. I've done it a couple times, and it works well, but I'm just too used to a mouse and keyboard, making it harder to player this game with a controller.
I think the main point the thread was trying to address was better in game functions for clan functionality, to promote the console players to form clans and be competitive, as opposed to endless pub lobbies. I believe it was mentioned that a lot of current console games already have a thriving competitive scene, as a lot of the newer consoles give players tools to network with each other.
