In my current (1.04) game as Mecklemburg, Holstein won their initial war with Denmark and took Jyland and Iceland. Unfortunately for them, they were later conquered by Sweden, though I did eventually "liberate" them.
In the same game, the Ottomans took Thrace, but then got stuffed and lost all their other provinces early on. Venice is very big in this game, and I watched for a long time for Venice or somebody to annex the Ottoman, but in the 1660's they were still around and picked up a couple defecting provinces.
France also annexed Poland in this game, but otherwise aren't doing particularly well in Europe.
