That fembot is Red Alert. She is in Rodimus' team, and they should appear more in this season, along with Strika's team. They were both featured in the 24th issue of the Club's magazine if you have 'access' to a copy.

At least Omega isn't dead, just back in the state he was for the first 28 episodes. Pity about Blurr though. Hope that isn't the last we see of him.
The new 10 characters at the start were interesting, but I fear that we won't get too much character development on each, as the focus remains on the Earth team. I would have liked to see more of those two new teams.

The Sari upgrade was a bit weird. I wonder if they will reveal where the protoform came from.
And it looks like Megatron and Starscream's head are still out in the galaxy somewhere, allowing for more non-Decepticon-focused episodes while the army waits for their leader's return before doing anything.
Still bummed about there only being a handful of episodes before a 2 or 3 part finale, which may be the last we ever get. Sure, it hasn't been my favourite TFs cartoon, but it is still entertaining to watch, at at least means we get some sort of TFs goodliness on TV.
