Here's the packaging for Persona 4 The Golden, as posted at Famitsu.com today:
Famitsu's e-Commerce site Ebten will be selling a "Famitsu DX" version of the game. This includes posters and other goods, with illustrations from Madhouse and Hiroyuki Maeda.
The sketch is from Madhouse. The giant question mark is apparently hiding some unannounced feature.
