I have checked in an internal documentation in PTC R&D about eyewears hardware supported.
Epson Moverio BT-300 is not supported in Vuforia Studio.
About the future support, I am asking to Product Manager and I will come back to you when I will have an answer.
I have received more details from Product Management about support of Epson Moverio Pro BT line of devices.
Today, they are not supported and no support is planned in a future release.
