I think this needs to be suffixed (2017). The latest spec version (1.12) is dated August 1, 2017. And there isn't any newer press release. That being said, Mellanox did in 2018 announce a static demo of an OSFP module (http://www.mellanox.com/blog/2018/04/first-showing-mellanox-400g-sr8-osfp-transceiver/ http://www.mellanox.com/blog/2018/04/first-showing-mellanox-...), but I don't see any products listed. Nor do I see anything from Cisco. So, my guess is that QSFP-DD has won. Either that, or (if OSFP does have better heat dissipation) OSFP will only be used in long-haul applications.
