The patch and Protector Trials had been scuttled because they were too buggy when 2K's deadline for them hit. Minerva's Den (which we liked a lot on console) just wasn't done. Following a rash of fan feedback and an unexplained change in resources or priorities, 2K Elizabeth says work on all of that is being resumed.
2K estimates the patch and Protector Trials will be out in December and will offer them for free. Minerva's Den's schedule is more murky, though 2K Elizabeth says the team is committed to finishing it and releasing it.
