I think that while some languishing teams are hoping for a shake-up that benefits them, what will actually happen is those with a lot of money (like Mercedes, Red Bull and Ferrari) will benefit and do better than everyone else because they have more resources and expertise to build a better car out of the blocks.
I won't be surprised if Mercedes still dominate next year.
Could hurt Merc perhaps that this year they're going to be developing to the very end with this year's car as well as designing/building the 2017 spec car, Ferrari might just give up and plough more time into next year's car, certainly looks that way. I don't think they'd care that much about 2nd or 3rd place if it meant next year could very feasibly be 1st with a bit more time spent on it than the others.
