Well, both in previous announcements and during the Melbourne shareholder presentation last year, it was mentioned that CETO 6 is the commercial model and the sole purpose of CETO 5 was to prove the technology worked at full-scale and to inform the design of CETO 6. So there won't be any orders for CETO 5.

In the latest announcement, they said CETO 5 will run until the end of 2015. Data collected during that time will inform the final design of CETO 6, therefore the CETO 6 design won't be ready until at least end 2016, although last time the design stage took 2 years. Then they need to build and deploy (another 1-2 years).
The earliest time to expect an order in 2018.
