its all speculation.
i wouldn't even buy in the first VR products.
the amount of change that will happen when they launched in a first 6 months to a year will be massive.
think about the product.
for the companies to make money they need to sell. how many will buy with the top end too expensive pcs needed? a very small percentage. so they will not recoup their money back. not until the software kinks processes is less expensive. the companies have billions invested.
so unless you have a very big bank account ready to be emptied every 6 months wait until its worked out.

.
you dont buy on a hope or speculation it will work. that's good for businesses . bad for you.
