Due to be operational on the James Clerk Maxwell Telescope in early 2006, SCUBA-2 will be the first 'CCD-like' camera for submillimeter astronomy. With over 12,000 pixels in two arrays, SCUBA-2 will be able to map the submillimeter sky up to a 1000 times faster than the current SCUBA instrument to the same signal-to-noise, and reach the confusion limit in only a couple of hours. SCUBA-2 is expected to have a huge impact on many areas of astronomy from studies of galaxy formation and evolution in the early Universe to understanding star and planet formation in our own Galaxy. Crucially, SCUBA-2 will also act as a ``pathfinder" for the new generation of submm interferometers (e.g. ALMA) by performing large-area surveys to an unprecedented depth. In this paper we present an update on both the array development and the instrument design over the past year.
