There's not really enough data to go on yet, but Fairplay magazine has posted ratings from the first day. Almost no games have even 10 ratings yet, and none have 25 yet (the minimum I prefer to use). So we really should wait a few more days.
But who can wait?!? :-)
OK, if I set an absolute minimum threshold of 5 ratings (which could come from a single playing of a game!), a few early winners & losers reveal themselves.
Winners (rating 8+): Geschenkt, Niagara, Carcassone:The City, Piranha Pedro, and Master Thief (Meisterdiebe)
Losers (rating 5-): Frantic Frankfurt, Popeln, Schatzbold
