You still need taskservice, but 5.2 gives you a couple more options 1.) Local task service and 2.) JMS based task service, in addition to Mina task service option
Here is an example to local tesk service http://community.jboss.org/people/bpmn2user/blog/2011/11/14/jbpm5--local-human-task-example#comment-8585
You, however, need to modify the console code if you want to use local or JMS based task service. It is bundled with Mina task service by default.
