Penguins and Kings have been discussing major trade. Has there been any progress?

Talks have continued between the Penguins and Kings. A source says the Penguins have increased their offer, while LA on the otherhand hasn’t. They are still offering Frolov and Kyle Calder. Pittsburgh doesn’t want Calder. The player the Penguins have included into the deal is believed to be Pascal Dupuis
Will update when I hear something new.
