There is every reason ( based on it's capabilities and what it actually did in Thor 2 ) that the Aether is the Soul Stone. The reason for it NOT being the Reality Stone is that it would do a lot more altering things. The only thing the Aether altered in Thor 2 were the beings who possessed it internally hence the reason for it being the Soul Stone. To date though the Aether has NOT been confirmed to a specific Stone by Marvel.
