Terabit Ethernet or 1TbE is a phrase used in current media to describe the next possible speed of Ethernet above 100 Gigabit Ethernet speeds. Facebook and Google, among other companies, have expressed a need for 1TbE. Some think that 400 Gigabit Ethernet is a more practical goal. The current reporting is that the target date for Terabit Ethernet is 2015, and talk of 100 Terabit Ethernet by 2020. UCSB has attracted help from Agilent Technologies, Google, Intel, Rockwell Collins, and Verizon Communications to help with the research.
The IEEE has announced the formation of "IEEE 802.3 Industry Connections Ethernet Bandwidth Assessment Ad Hoc," to investigate the business needs for short and long term bandwidth requirements. They plan to formally announce reports of findings the first half of 2012. 
IEEE 802.3's "400 Gb/s Ethernet Study Group"  has started working on the next generation standard in March 2013. Results are expected by 2017.
