Yes, DiVine is still at AK. As for Epcot, the Jammitors still appear in FutureWorld (pretty sure they were there ten years ago). In World Showcase there will be quite a few new things - Bodh’aktan in Canada, the British Revolution in the UK, Musique Aramenco in Morocco, Voices of Liberty in the US. There is a Bavarian band in Germany.
Serveur Amusant is still doing his thing in France, the Matsuriza drummers are still in Japan and Sergio is still juggling in Italy. The acrobats in China are still going, as are the Mariachi in Mexico.
The one thing you might miss (I know I do) is Miyuki (the Japanese candy lady). Shiny shiny caramel...
Hope that helps.
