Famitsu is promising a feature on Kingdom Hearts 3D for next week's issue. A blurb in the back of the magazine this week says to expect details on the game's new worlds.
The next issue of Famitsu officially hits on the 24th. Famitsu info usually leaks out one day in advance of street date, although because Wednesday is a holiday, we may get the details as early as Tuesday.
Kingdom Hearts updates often include interviews with Tetsuya Nomura, and Tetsuya Nomura interviews often include little bits about Final Fantasy Versus XIII. It's fast approaching the time when Nomura should tell us that Versus XIII won't be at this year's Jump Festa, so even if you're not into Kingdom Hearts, be sure and check back next week!
