It won't go mainstream for YEARS. That's why I said 10-15 years before everyone has one in their home. I've never said that it would go mainstream in such a short amount of time.
There are going to be 3 stages to mainstream adoption:
1) Enthusiast gamer adoption. People like me who buy high end PC components to build a new machine every 3-5 years. This demographic is quite happy to pay a premium price to become an early adopter. This is the stage we're at now.
2) Mainstream gamer adoption. The type of gamers such as your good self who build or buy a mid-range PC for gaming and play mainstream PC and console games such as GTA, Assassin's Creed, CoD etc. Most of these people won't want to pay a premium price to play in VR, the sweet spot is around 200-300 quid/dollars for them to buy in.
3) Mainstream consumer adoption. Your average household that doesn't necessarily own a PC powerful enough to run VR. The sweet spot price for this demographic is under £100. This demographic is the hardest to crack because the technology currently isn't there to have a powerful and decent standalone headset at a decent price. The Oculus Quest is an ideal type of headset for this group but at £399 It's way too expensive.
As for GearVR that's at the low end of the spectrum in terms of quality. It's a 3DOF headset so it doesn't have positional tracking, could be why you were having issues with simulation sickness.
Like I've said, you'll understand exactly what I'm talking about when stage 2 of VR mainstream adoption happens. It's already started to a certain extent with PSVR, and will continue when Microsoft eventually jump in and have it on their console too. It's not going to be high-end, PSVR is mid-range VR due to the tracking, and I'm fully expecting Microsoft to cock things up as far as the hardware is concerned just like they did with Kinect and HoloLens lol
As for motion controls, they're a key part of VR and once VR is adopted by mainstream gamers such as your good self you'll see very few gamepad only and non-VR games being released in about 5-10 years time.
