Tetsuya Nomura sat down with Famitsu and, among other things, talked about that mysterious trailer unlockable at the end of Kingdom Hearts 2. You know, with the apparently more "Square-Enix" take on the franchise? Those knights seriously look straight out of the designs from Final Fantasy IV. We know that Kingdom Hearts 3 exists, but up until now we've had no idea what to even look for.
Nomura admitted that there are plans to give some visuals of the next KH before the end of 2007. You can speculate that the Tokyo Game Show will reveal a trailer, images, or just some printed information. Not much else to say, but feel free to toss in your theories or ideas here. I had a really good one, but... it's been a while and I've forgotten what it is.
