IMO the jungle feels really stale this season. It was/is basically 
Junglers or 
/
with a tiny splash of ap junglers like 
. Will it be different next season or the same as this season?
There'll be some changes yes. Tweaks to jungle items (balancing more than reinvention), adjustments to jungle camps (creating stronger contrasts between single target and multi target junglers to enable different strength profiles) and some other stuff that's not yet ready to be talked about.
For the last 2 seasons they completely changed the jungle each time to make it significantly more difficult on junglers. I can easily see them continuing that tradition and doing something diabolical like making starting jungle items cost 500 gold so we can't even buy health pots next season.
