Yes certainly changes are coming. With the onset of oracles and communities other Dapps will have the ability to implement algorythmic rules that take away the abilty to use delegated votes or any other criteria that they desire.

For example, you may find a new niche in a Dapp that serves photographers.

Of course all new Dapps will need Steem as the underlying currency in order to have bandwidth which will make all existing Steem coins more valuable.

This is how I understand the coming changes.
