When? There are no more fan fests. The best you get is this:
"Currently there are no plans for a third job. Of course, there are a lot of people, myself included who are looking forward to new jobs. Creating an unbalanced job or ruining existing balance is something we don’t wanna do. We’ll revamp the system in 4.0, balance it, then maybe we’ll make another job."
Which is Yoshi P being grossly optimistic at best, and politely declining at worst.
