I understand the Conservative party believes that they can force him out if they win the next election. This is why they don't want to force him to resign right now - they would prefer to have a majority in the Commons to allow them to choose the person they want rather than get another person picked by Labour. I have no idea how, under the Parliamentary rules, they will do this, but this situation has been much discussed on Radio 4 without anyone suggesting the Speaker could hang on in these circumstances.
