For Now, Have All The Screenshots

Namco Bandai have announced a platform-specific closed beta that starts on October 5th, though vexingly haven't revealed how testers can register. They've promised to do so via social networks, so we'll keep an eye out.
In the meantime, here's an enormous heap of screenshots direct from Cologne.
