H.265 with BMD 10.5.1 update

On or about Nov 17th, BMD tweeted out that Desktop video 10.5.1 was adding H.265 encoding to the UltraStudio 4K Extreme. At the time, I responded with a question: "Will H.265 encoding support be forthcoming on the (plain vanilla) UltraStudio 4K?"

The original tweet by BMD was subsequently deleted and then reposted a couple of hours ago:
"New Desktop Video 10.5.1 Update. Adds H.265 encoding support for the new UltraStudio 4K Extreme. Download now!"

It would be appreciated to get an up-front response from BMD on whether the plain vanilla US-4K will be getting H.265 support.

Bruce -
The Ultrastudio 4K Extreme (2 rack unit high product Announced NAB 2015) has a very different architecture internally and is the only product capable of H265 encoding in our Ultrastudio product line. The original Ultratudio 4K (1 rack unit high) is not able to do H265 encoding as the architecture and technology are NOT present in the product you mention in your post.
