I don’t like the idea of console games REQUIRING a keyboard/mouse. Optional sure why not. But I prefer console because of controllers.
It was a quote from Phil Spencer I read somewhere...I would assume that developers would give the choice in their games released on Xbox...much like what's available in the majority of PC games at the moment. I play most of my games with an Xbox controller on PC unless it's a flight sim..or something like ARMA even though M/KB is available too.
The majority of the AAA games released on PC have native Xbox controller support built in anyway....stuff like all the Assassin's Creed games, all the Tomb Raider games, GR Wildlands, R6 Siege, Battlefield series, CoD series, The Division or The Witcher 3, ESO, Fallout, FIFA etc. It wouldn't be a far stretch to have exactly the same KB/M options in the Xbox versions as we have on PC.
In fact the main differences for me playing those games on PC as opposed to Xbox is the amount of graphics/quality or controller options I have...that and modding.
This isn't the quote...but one similar.
"There are certain games out there that require mouse and keyboard and they can't come to console today," Spencer said in the video. "If we put this capability in the hands of developers, we'll get more of those games."

If I find the actual quote, I'll post it.
