Looks like Johnny's was pretty worried about the competition for Over's release date as there is now a 2nd LE edition, this one coming with the Born on the Earth track and a DVD with a clip for Ai-ing -Aishiteru-. CDJapan already has the pre-order sold out but I'm sure it'll eventually come in stock again. Or at least I hope it does as I didn't get the chance to add it to my order.
EDIT: And they've also attached a special campaign to the release where each edition comes with a user code that you can use to download a special message from the boys, each code is good for one message and each boy will have three messages each. Though I'm not sure if you download from the PC or if it's just for the cellphones, which would mean overseas fans are SOL.
