Based on what I've been seeing ever since the original announcement last fall, the 60 day timeline is the contractually-defined minimum duration between launch of the R-972 and the launch of the 997. That means that if Sherwood officially launched the R-972 tomorrow, Outlaw would have the option of releasing no sooner than September 30 - but they would also be able to wait longer if the firmware still had some "joy buzzer" issue (to use Peter's great comment) that Sherwood had gone to market with but that Outlaw wasn't willing to tolerate on launch day.
