I see your point but it would seem new enough to be all the buzz either way. In the event that they release it earlier than later, they can demonstrate a strongly rising stock price to new eyes.
I can sort of see your point but I do disagree. I think they should announce full commercial of Namoya a few days before the conference so that there is a buzz. That way Media will have a heads up, Media also will be more focused to listening and viewing Namoya presentation, more will be in attendance that way.
