But they're not downplaying the PT. Hell, the Catalyst novel that leads into Rouge One, begins pre-Clone Wars, then shows during the Clone Wars and then up until the intro of Rogue One. Leia visited Naboo in her comic series. When Vader learns about Luke in his solo series, they specifically show him having flash backs to Episode 3. Hell, had they kept in the Senate scene in The Force Awakens (the scene is canon as it is the novel), we would have seen senators from planets only seen in the PT.
Hell, Cassian Andor in Rogue One was a Separatists during the Clone Wars.
Spoiler for Rogue One...
Mustafar from Episode 3 appeared!
From TFA...
Phasma wore armor coated in chromium salvaged from a Naboo yacht once owned by the Galactic Empire's Emperor Palpatine.
Also they directly reference the Clones as we know them in the PT.
alright. i'm going to be honest, i don't understand most of the things you just referenced. if you want to tell me Phasma's armor was made out of that extremely non-star wars looking spacecraft that's fine. if you want to tell me that IG-88 took over the death star and trapped the emperor in a bathroom by hacking the doors .. okay fine.
as long as the references to the PT or new canon expanded universe are things that seem only like fanfic stuff to me, that i won't even know or notice, i'll be fine. if those references are in there to make y'all happy, that's cool. i just don't want any trade federation droids or robo ninja jedis.
