Transformers: Til All Are One has been cancelled.
From what Scott says, the numbers just weren't there, which is a shame. I still haven't got around to picking up the first volume of it (nor Titans Return), but I read the preceding Windblade minis and they were... ok. They weren't helped by some sub-par art (but TAAO's artist Sara P-D is good). The biggest problem for me was that Scott felt like a second-string stand-in for Barber. I was quite disappointed when the Cybertronian politics elements of RiD got edged out for yet more stuff on Earth and even more so when Barber decided to stick with Earth and hand off the rest.
Between a stupid shared universe, cross-overs and this cancellation, I fear IDW are in danger of (yet again) screwing up their Transformers comics.
