No, they've said they are going to take preorders as long as people want them, they'll just have to push back the ship date on later orders. Last I checked current sales ship out in May.
The Galaxy Gear VR or whatever it's called, when you think about it, it more expensive than Rift or PSVR. You need the Gear VR device plus a compatible smart phone to fit in it. To my knowledge, those "compatible" phones cost nearly $700-800 either unlocked or factoring in how much your contract is going to cost you to subsidize the cost of the phone.
I don't know what the requirements are for the Rift, if someone will post that, that'd be awesome, but I have a gaming PC, I figure that's probably good enough. I'm willing to bet the Rift's "requirements" are based on playing EVE: Valkyrie, not watching porn in VR or minesweeper or netflix or whatever other really simple things people might reasonable do with it.
Taking preorders for as long as people want them doesn't really change anything. It's still your hardcore early adopters buying them.
System requirements for Oculus Rift:
◾Nvidia GTX 970 / AMD 290 equivalent or greater
◾Intel Core i5-4590 equivalent or greater
◾8 GB+ RAM
◾HDMI 1.3 video output
◾three USB 3.0 ports and one USB 2.0 port
◾Windows 7 Service Pack 1 (64-bit) or newer
Those are hefty requirements for a peripheral that alone costs $600 plus shipping. I don't think you can run Oculus on "lesser" hardware because those are the requirements to make it function. So regardless if you just want to watch porn or play some casual games, the hardware has to be there for the Oculus to work with it.
The Gear VR is a niche product and I don't think anyone expects any different from it. It's a $100 system. Yes, you have to have a compatible phone from the Galaxy line. I already have that and the phone performs many functions I need or want, regardless of any desire to play a VR game. I don't see the point in bringing up the cost of a phone for a peripheral, unless you want to talk about the $1200 it will cost to buy a compatible PC to play the Rift.
