I watched the premiere today.
I don't know about the 40 minuttes thing, but sometimes when they air a new show the shows first ep will be twice a long as the regular eps to be able to introduce the show better and catch some viewers.
I think there will be more humans as the show goes along.
As I have only seen an ep here and there of the two other seasons of digimon, I thought it was neat that digimon only were a game and a show in season 3.
