Fortunately the two groups came together in the IEEE, and there are no competing standards.
IEEE P802.3bz 2.5/5GBASE-T Task Force stared in March 2015: - 2.5GBASE-T: 4 x 625 Mb/s over 100 m Cat 5e (Class D) or Cat 6 (Class E) unshielded twisted-pair copper cabling - 5GBASE-T: 4 x 1.250 Gb/s over 100 m Cat 5e (Class D) or Cat 6 (Class E) unshielded twisted-pair copper cabling - MultiGBASE-T auto-negotiation between 2.5GBASE-T, 5GBASE-T, 10GBASE-T, 25GBASE-T, 40GBASE-T - Automatic MDI/MDI-X configuration - PoE support including IEEE 802.3bt amendment (power over 4 pairs) - Optional Energy Efficient Ethernet (EEE) support - Standard expected in September 2016 - Interfaces expected on the market in 2016 - Task Force web page http://www.ieee802.org/3/bz/ You might have seen my Ethernet speeds presentation... the most recent one is here: http://ix.br/pttforum/9/slides/ixbr9-ethernet.pdf (December 2015) It's slightly out of date as the IEEE Interim was just last week.

I think they hope by avoiding IEEE int he early stages and taping silicon they'll get the job done quicker - the drive mainly being faster wireless APs and cheaper data centre interconnects... alan
