Just an FYI - I received an e-mail from Pawel at WidmoVR regarding the Odyssey Plus lenses. These guys did a great job on my Rift lenses, so I queried them about whether their Odyssey lenses would fit the Odyssey Plus:
“We are in the process of importing the Odyssey+. Unfortunately Samsung didn’t released it in Europe so it will take us few days until we receive it. After some research we are fairly certain that the regular Odyssey adapters will be fitting fine, but we need to be 100% sure. We will add this information on the product page, as soon as we receive the headset.”
