Around one or two mecha shows per season, perhaps even less after Eva 3.0+1.0 is a good movie but fails because not enough pandering and nobody cares for the controversy anymore.
More traps, definitely, or at least "feminine boys", every light novel will have one, and by 2020 most anime will be an adaption of light novels.
Creativity will remain with Studio Trigger but they won't have enough budget to create something that isn't Ninja Slayer or Inferno Coppu.
Imoutos and Onee-chans, Christmas cakes will become a standard in every show, Ara-aras will die out since Esdes failed so hard as a character in Akame ga Kill.
Once Monogatari Series ends there will be nothing left to even by hyped for, except Index Season 3, which isn't happening.
TL;DR: Light novel adaptions will be all that's left of anime, more light novels will spread to the west and get localised and light novel staples will become anime staples
