The knee-jerk is strong in this thread.
Why do so many people forget that Oculus wants to get VR into the hands of your average person and not exclusively gamers? This was their plan before the Facebook buyout. Hell, that was the idea before Carmack came on board. Also, Oculus being owned by Facebook had almost nothing to do with the bundled controller. Oculus and MS have been working together for a while now. The Rift will have native Windows 10 support and native XBOX ONE SUPPORT. The thing is designed to work on the Xbone and Windows 10 right out of the box. Microsoft didn't want to have to make their own VR headset when they can just add support for the most popular one. Them working together to bundle the controller is small fucking potatoes, compared to the rest of what they're doing together (if you want to get your panties in a wad about something anyway).
The standard retail launch unit has to come with some sort of input. I'm sure you'll be able to buy a standalone Rift unit if not at launch, then shortly thereafter. Not everyone wants or needs a controller. However, as someone that doesn't own a gamepad for my PC, and is very, very far from being sold on all the wacky tracking controllers, I'm glad to see this. I don't care how accurate they are at tracking, the Vive maracas and the Oculus controller-O's should be a hard sell for anyone at this point. And in that vein, I'm far happier getting an xbone pad (one of the best pads I've ever personally handled) than whatever goofy "this makes VR real!!!" hand toy they've made.
Not that I'm saying that the hand tracking devices won't be excellent, but for launch, I'll take a gamepad that will bump up the cost by a little bit, but is more universally applicable over paying through the nose for something that hasn't been proven in the average gaming experience. I'm sure that there will be plenty of other applications will prefer the precise hand tracking and gesturing, but I'm not a VR weatherman so I'm not worried about having to invest right now.
