I'm not saying anything for now, let's wait and see but so far, I'm not impressed. Well, 7x21 is technically not the series finale, so if they're not in this episode, it should be fine. I think Josh is still filming his pilot and Jennifer has 2 days blocked off this week for an event. They have all next week, plus a few days the week after to finish filming.

I don't know why they wouldn't announce any additional returns in the press. Like you said, they don't have anything to lose by doing so and viewership has already tapered off, so people aren't going to "wait and see" if they haven't been watching the season. Plus, Vancouver airport paparazzi - they'll likely be the first to announce if ABC doesn't release it to the press first, lol.
