With the reintroduction of the Barretta, there is definitely renewed hope for a mega scope (Though, as a mostly non-sniper, I'm sort of on the fence about this one). Higher scopes usually equate to more players hugging the far stretches of the map so the team will need to be careful; Tests have shown that while the community loves the openess BF brings, sometimes maps can feel a little too huge a la Hamada and the like (this was mostly a transport though IIRC).
The trailer showed off the new flash/concussion grenade so it's possible a night vision/IR scope could be added into the mix; would definitely help me see players better.
The colour theme for Prime rewards is purple so I definitely recommend checking that out if you can. A few late battlepass rewards are pruple and I think I saw some gold(ish) items in the store so it's probably going to be a theme rolling forward. Pretty much everyone loves shiny gold lol, makes things easy.
