I doubt AS3 will be this fall. Their post production and promotional shoots, tours, etc. push the shooting and premier by at least 7-9 months every single year. There's no way VH1 will not milk the show for it's worth, which means drumming up the excitement and anticipation as much as possible.
I think S10 might instead get moved to a late-summer or fall 2018 timeline. Nothing major used to play during summer, but it's definitely a trend started by House of Cards and Game Of Thrones and I'm sure VH1 would want some original programming which will have a sureshot audience.
As for the AS3 cast rumors - yep, that's going to be fun. I'm already torn between Team Trixie and Team DeLa. Some folks are also saying they might some AS1 queens back (Yarlexis and Manilla Luzon have done cancellations apparently), as well as Shangela - who's another very strongly rumored queen.
