A few weeks ago, the Penguins unveiled the logo that will be used as a part of the Stadium Series game vs the Philadelphia Flyers on February 23rd.
The Flyers logo looks very similar.
Today someone leaked the Flyers jersey from what looks like a shipment of youth jerseys to a store somewhere in the Philly area.
So after seeing this, it looks like the Pens will be rocking some sort of all black jersey with the gold logo presented above. I'm sure it won't be long before someone leaks the Pens jersey anyway.
