Hal, Great thread as always. I'll be going to the WPPI conference next week and I'll stop by Nikon's booth and ask them if there is any predictions as to when the next flash will come out. I'm not anticipating I'll get an answer. On Nikon's site I went and checked out when the various flash systems were released. The SB-900 July of 08; SB-800 released in 2003; SB-600 released in 2004; and the SB-400 released in 2006. If they release a new flash every 2 years, could we anticipate a new flash being introduced this coming summer?
