Yes there will be a season six of criminal minds. It's rated third in topo, início police procedural shows in the world. Criminal Minds gets about 1.3 million viewers each episode, that's even reruns. Not actually proved that there is going to be season six, but my best guess is yes.
There will be a season 6, but CBS is planning to remove AJ Cook and Paget Brewster's involvement. Many sites (link) have petitions, as well as a face book group (Save the girls, save the team, save the show) to try to stop this from happening.
