One of the new event scenes in Persona 4: The Golden is a ski trip, which takes place in January. When you get to the mountain Teddie says he’s freezing cold and dresses in skiwear. (I imagine he’ll say "Brr… it’s beary cold!" in the eventual English release.)
According to Famitsu, all of the characters have new winter outfits. Chie has a green jacket with fur. Yukiko wears a brown coat and red muffler. Yosuke has a parka over his school uniform. The protagonist has a white pea coat and a blue scarf. Characters can wear their winter styles during battle scenes, just like how Yukiko can dress up like a maid and Chie as a martial artist.
The winter event will have anime scenes, like one with Yosuke and Chie snowboading. All of the other characters ski. This will be a multi-day event where the characters spend the night in a lodge.
Persona 4: The Golden actually has five difficulty levels (we reported four last night): Safety, Easy, Normal, Hard, and Risky. Safety is designed for players to enjoy the story and Easy is made so players don’t have to worry about a game over screen.
