We'll talk when it actually ships.
You do understand 3k is a ton of money right ? The other issue is even if I did pre order , the second you miss a release date I'd file a charge back.
Get too many charge backs and payment processors will stop accepting orders for you.
To be honest it would make more sense to develop an ultra cheap option, anything 1k or less, and you'll find people ready to take a risk. You might still get in trouble if you miss your ship date though.
You can buy an HTC Vive for 800$, and a PI4 for 60$. Where is the other 2k in markup coming from ?
