The only way that Hales will get in the side is an unbelievable winter of ODI cricket with tons (literally) of runs under his belt where there's no other choice than slot him in the side. Otherwise, I'd expect an already capped player or Adam Lyth if he carries on into the start of the new year.
I think the bigger question is what will the Australian side be like? Will Rogers make it until then, the India series could be it. I fully expect the Australians to run India all over the park on their own turf personally.
