Interesting. I do remember hearing some speculation (or maybe it was based on something Filoni or someone else said) that we would see the Jedi purge to some extent. Considering that scene comes right before Order 66, I imagine this will probably end up being true. But to what extent? If I had to guess I’d say we’ll see Captain Rex’s perspective? Don’t really want to show everyone getting murdered on a kids show (plus we’ve seen it in the film anyway), and Rex will show a different side of the event that will lead into Rebels. Well, I guess we’ll have to see Ahsoka’s perspective as well.
I will say, if they’re going right up and into ROTS, that’ll make the fact that they just sort of dropped into the Clone Wars halfway between AOTC and ROTS even weirder.
They kinda had to - Anakin was still an apprentice in AOTC, so it doesn’t make much sense for him to suddenly get a padawan (they wanted to start with Ahsoka to give new audiences a character to latch to).
Also Ep 2 wouldn’t bring us much. ROTS has interesting concepts to explore from the other perspective.
