First past the post is likely to remain

First past the post is good for the government so it will likely stay... since it is the government who decide these things. Whether or not the people prefer pr is academic because (if people keep voting for the two 'government' parties) it is a decision for the state and we cannot expect (even the benevolent state) to act in its worst interests. The state will protect itself which is why it will choose to retain first past the post.
