PS3 had built-in motion controls. Xbox 360 had arguably the best ergonomic controller of its gen. Wii had innovative motion controls.
PS4 had the touch pad, light bar, and share button. Xbox One refined their Xbox 360 controller. Switch had portable gaming and improved rumble.
I personally thought Nintendo had the most interesting changes. The PS4's touch pad and built-in speakers are hardly of consequence. The share button is the only new addition that was significant.
What do you think the next consoles will have? Do you think the next updates will be of consequence and significantly influence gameplay? Or will they play it safe and stick with current designs? Are there any current gen controller annoyances that you want gone?
