Not really. I mean the Soviet Empire wasn't replaced with a new Empire. It broke up into its republics -- mostly because they didn't have a strong national identity. The Ukranians or Georgians had no interest in the revival of Russian Empire. The Caroligian empire also wasn't a direct decendant of Rome. It could happen if the Empire has a strong national identity based on being THE EMPIRE OF TAMRIEL. Outside of Cyrodiil, it doesn't exist in that way. It's a lot like the USSR, and while the Empire might survive as a government in Cyrodiil, outside of Cyrodiil, it doesn't have enough loyalty.
I think he was talking about the game history. There have been 3 Empires in the game lore that have all been based around Cyrodiil. I agree with him in that a new leader is likely to rise up, gain the respect of the other provinces, most likely the human provinces first, and build a new empire. And even for real life, your missing out important examples like the Eastern Roman empire becoming the Byzantine Empire, which was then deposed by the Ottomans, or The Holy Roman Empire splitting into different kingdoms, and then some of its territories being reunited by Otto von Bismarck under the King of Prussia, who became Kaiser (Emperor) of Modern Germany.
