Yeah, I kinda think PI let it die on the vine. I tried to use PI a couple years ago when I still used a Palm device. PlanPlus was a really good Outlook add-in by Franklin Covey that supposedly worked on BB devices through PI. I could never figure out how to use PI, though. I've since moved on to ToDoMatrix Professional. Works really well, but I do miss Outlook integration. Conqu is another promising app for the PlayBook, but a BB version isn't available.
