The NA Reform experiment has been closed and under wraps for a while now, pretty much a day or two after Wookieecookie announced it, they had closed off the application process for having the desired sample size.
Beyond that, we were also told that they wouldn't update us on the progress or whether or not the experiment was a success. No matter which way the experiment went, we won't know until the hypothetical scenario occurs where a new one starts, which, frankly, would be unlikely.
Would that there could be better news - or, news for it at all - but as far as we're concerned, even if the results came back conclusively positive, I'm doubtful they would have extended the trial to others/an increased sample or done much further in that line of testing.
