I don't know if this has been mentioned before or not, but CDJapan (
www.cdjapan.co.jp) has listed a special metal accessory tray to be included with RAINBOW for those who pre-ordered early enough.
Here's the link to it:

They haven't released any information on what is to look like, but I'm guessing it will have the A logo or something similar on it. Also, I'm not sure if this is a bonus which will be included with all first-press, or if it is just an exclusive thing @ cdjapan. I've had my two copies pre-ordered since the day that they put the link up.
Something also related to this.. I had pre-ordered my copy of "Voyage" like a month in advance from CDJapan, and I got a "Tsuki ni Shizumu" promo poster included. Did anyone else receive a poster as well (but didn't order off CDJapan)?
The anticipation is killing me >D
