It's interesting but seems far fetched and for the most part just taking advantage of the people that want to see this game become a reality. They claim to be working on their own version of the famous "nervegear" as used in the anime sword art online but in reality what can they do and are they even working on it?
They have no ties to the oculous rift or the Sony VR headset so they are going to try and create a similar product out of nothing posting nothing more than a google image of the nerve gear from SAO as proof? sketchy to say the least.
I am a huge fan of SAO and watch the new episodes that come out weekly but I can still see where people are taking advantage of others just because they want to see something like this become a reality.
Oculous Rift is going to go to shit now that Facebook bought them and will most likely be used in the beginning with Facebook mini games and social media type interactions. This type of headset is no more than a computer screen an inch away from your eyes, I can make that a reality by learning forward a bit, so really nothing special. The technology that anyone that knows anything about Virtual Reality would include a fully submersable VR where you are the character in the game not still using a keyboard/mouse, gaming controller, or treadmill while wearing a computer screen on your head.
Thanks for the post though even though it may seem that I am over analyzing it or being judgmental it in no way refers to you only the piece of shit companies that will delay the true science that is required to make this a reality just to milk the eyeball tvs as much as possible. We would be lucky to have anything close to sword art online in our lifetime but the sad truth is there probably wont be, now get to class and prove me wrong!
