With the exception of the anonymous buying reported by FJ, there appears to be an influx of many new buyers. Perhaps we are now getting a return on the IR dollars spent. Perhaps the recent news release has given greater credibility to product development now and for what is in the pipeline.
This may explain why there has been no news. If there were a leak of material news, frankly I would anticipate an even bigger spike so the new product announcements may have finally convinced some to jump on board.
