Almost all of the pubs round my neck of the woods open till midnight now - and usually there aren't many people in them by that time. So I don't think there's much call for late-late-late licences, at least in my town, and I just can't see landlords being prepared to open till four in the morning or whatever. I used to work in the licenced trade myself and the staff and management couldn't wait till 11 o'clock! They have homes to go to as well!
