We dont have much infomation on Cantha after the Emperors successor rose to the throne. We know that he spent millions of gold Building and Arming his army which then went and conquered and forcibly ended the war between the Luxons and Kurzicks.
We learnt through the Booklet that arrived with EOTN that life was returning to both there homelands, so I'm guessing that after 250 years life will now have completely returned.(This also goes with the fact Anet has drastically changed the looks of the 2 other continents.)
The Emperor who has taken Cantha Usoku, is described as a Tryannical and Fierce. He also drove out everything non-human and acts more of a modern day dictator than an emperor. (It can be assumed there will be underground movements with creatures such as Tengu within them.)
I am going to guess Cantha if it is still Isolated seeing how the rising of Orr ended the links with it, will be a modernised country where on the surface all looks happy yet on the inside all is the exact opposite.
