It happens every product cycle. Despite Microsoft's best efforts to keep details of its launch plans under wraps, an online retailer has leaked pricing for OEM copies of Windows 10 and Windows 10 Pro and is even accepting pre-orders.
The details appear at Newegg.com, where a search for Windows 10 turns up two OEM System Builder packages for sale.
Windows 10 Home OEM $109.95 Release Date: 8/31/2015
Windows 10 Pro OEM $149.95 Release Date: 8/31/2015
Edit: I just noticed that one of the requirements for the install is a Microsoft Account. Hopefully it will give you the option to install without the account like Windoows 8.1
