The next batch of 0.4m telescopes are nearly done being built and have begun to be wired up. The current plan is that the first pair will be sent to Haleakala at the end of March 2009 (where they will be housed inside the FTN clamshell), the next pair to Siding Spring at the end of April 2009 (housed inside the FTS clamshell), and one telescope going to Cerro Tololo mid-late summer 2009 (with another one to follow soon after). These will not be released onto the network right away as the network software needs time to be tested.
