Well, judging from past decisions made, I wouldn't put it past the higher ups at SONY and NBC to buy into the EJ-Sami leaving theories despite the reality that the show was on the brink of cancellation way back in 2008 in midst of their relationship, and that the ratings over the past couple of years during the lock stock and barrel storyline were mediocre at best. In fact, the best ratings boost that the show has gotten in the last year or so came when EJ got involved with Abby. I'll say it again, changing writers will make no more difference than it has after the past three regime changes, until the suits change their mindset on what they seem to think viewers want to see.
