I don't know how soon that will be possible while still making a profit on it. For the product to perform as well as it does requires expensive technology. The iPhone 15 Pro Max is $1,200. I don't think it is possible to make a vision pro for only 50% more and turn a profit.
I would think they'd lower prices before cutting production if it would be reasonably profitable to do so. While I think that there can be some really cool applications for high end AR/VR, I don't think that using them to create a virtual movie theatre is a great use.
I could see some really great applications in creating attractions but the cost per unit, especially with the abuse they would get in daily use at a theme park, is too prohibitive.
