QBasic sent over a picture of an advertisement (thanks!!), which appears to be a silhouette of character holding an evoker. Juan points out in the comments (also thanks!!) that RPGamer is running the ad and it has an active timer ticking away until Monday morning.
The art oozes Persona 3 and announcement about Persona 3 FES seems likely. However, Atlus is giving this an unusually high amount of hype. Perhaps, they have a corresponding surprise like an announcement regarding the anime, a Nintendo Wii port or a limited edition package to go along with it?
