It was a pretty short 6 episode run for this batch of season 9 when the season is almost done. There's 12 left and usually they do airings into May the past seasons with an event airing in July. This current season 9 even did a straight run from March to May of 13 episodes in a row (oddly followed by 1 in June then 5 in one day in July) when it first premiered.
Hmm, but if they're trying to hold off to July or August, they could be doing that to position season 9 to roll right into season 10 in late fall this year. To further that theory, since season 4, the even-numbered seasons have all had an October premiere. So they could be saving up this last 12 for a July 11-ish start (in the remaining 12, there's 1 2 parter and 1 3 parter so they could do the former in one day for example and it would be an 11 week run) and end season 9 around September 19 or 26 and hypothetically premiere season 10 on October 3 or 10. So you could be onto something with no new TTG until July (and concluding in September then the new season starting in October).
