No, PBS does not build the pairings unless they go with Jeppesen and use their Calibrator (which they won't because it's by far the most expensive option). The pairings will stay the same, PBS simply builds the lines from those pairings. PBS is all about work rules and since those have not been negotiated yet, it is impossible to predict how it will work - apart from the fact that you'll still do 98% 4-day trips, because those are built independent of PBS.
You already see the first effect of "min day pay" - The pairings are built with more front and back end turns decreasing the number of commutable lines. No more 1-2-2-1 bliss. PBS has no effect on that.
