Yeah... I just went over to the hockey news this morning and noticed it's not there this year. They must have collected their stats from one of the sources (NHL.com?) that stopped putting that info in their box scores.
That was one of my favourite tools last year.
Though now, I check a box score every night to the point where I have each team's PP1 & PP2 units in my head just from viewing the night PPTOI numbers using ESPN's box scores.
