HDMI board and HDCP 2.2 compatibility ports

Does anyone know if there are any plans to increase HDMI ports that support HDCP 2.2 beyond the one currently available from port 8? I am planning to purchase a 4K Blu-Ray player which requires HDCP 2.2 and I understand when Sky release the 4K update to the Sky Q Silver box this will also require HDCP 2.2 for full 4K compatibility. So two ports offering this becomes the minimum requirement. If this were to be offered in future would this be via a firmware update or through some other means? Having just spent £1200 having my HDMI board upgraded to the 4K board I hope I am not going to be caught out.
