A major upgrade isn't coming out soon, but regardless, when you buy a perpetual license you get the current major version along with the next major version. See "What updates am I entitled to?
" in the perpetual license section of the Purchasing FAQ.
A new "minor" version will be out soon. Really, all the minor updates since RightEdge 2010 was released taken together could easily make a new major version or two. Some of the major features added in these "minor" releases were multithreaded optimizations, optimization plugins, custom watchlist plugins, and systemwide margins. The next build will also allow system results plugins to save images of charts.
