By the way, in reply #8, I posted the NBP's issue schedule for 2014. See how there is no info yet about a certain coin that could come in April? (Clip attached.) Well ... April 2014 is when two Roman Catholic popes will be canonized. And one of them is John Paul II ... hmm. 
And yes, there will be several coins next month that commemorate the canonization. Attached is an image (from the central bank's website) of the 2 zł piece. However, in about four weeks (15 April), there will be four denominations ...
500 zł silver (Ag 999)
100 zł gold (Au 900)
10 zł silver (Ag 925)
2 zł Nordic Gold
