Hope there will be a new one. The series always has had these long breaks between seasons since Tamers ended. I liked Xros Wars, the change of how the world works and an actual competent main character made the season really good. I'd put it in my Top 3 with Tamers and DA01.Other than Digimon Fusion/Xros Wars (which is over in Japan) nope.
Edit: Awesome, top of the page in a Persona announcement thread talking about Digimon.
