I don't think big blender moves will ever be "in" -I think most people view moves ending with blenders as fairly cheap for their add value - ie. pdx blender is an easy 5 add move, spinning pdx blender is an easy 6 add move, spinning ducking blender is an easy 7 add move (compared with other moves of their add value).
Definitely there is a growing trend towards hard low add moves and creative moves. I also think there is a move away from shuffle and back towards downtime genuine play. Also more focus towards links - ie blurry whirl>ps whirl is considered very standard while ps whirl>blurry whirl is a more common combo.
I don't think dynos will be in.
I think repeats have run their course, I think ppl will still look to bsos moves in runs but at the same time mix up the order more to shift the focus to variety and tough/creative links
I hope symple will be all the rage.
want to see more downtime legeaters, symple tricks and stallbergers (especially something like predator-berger or bedwetter-berger - those are hot indeed).
