Microsoft's Phil Spencer has said that one day motion control implementation in games will become the norm, just like multiplayer.
"Much like with multiplayer, I think it will become the norm," Spencer told Kotaku. "If you are a racing game without multiplayer the game just didn't sell.
"We think that motion control, we think voice recognition, should become a part of gaming as well."
However, Spencer says that not all games, initially, will not get Natal support.
"Hacked in or quick to market ideas are not what we're looking for," he said. "We want to make sure that those experiences are world class."
