User blog comment:MahApplez/ I CAN GET THE V3 AND V4 EDITOR???/@comment-32500188-20141213213503

Like Serza said, that offer is only valid for those who purchased the V3 editor on the Japanese side:

"日本国内の販売店でのご購入、かつ日本国内在住の方に限らせて頂きます. "

"Purchased from Japanese distributors, and limited to residents of Japan."

Mentioned in the "ご注意" /"Please Note" section of the upgrade page.

Also mentions that you'll have to have your proof of purchase in order to be eligible for the upgrades, so this may even be a little difficult for some of the Japanese residents to get, especially if one is unlucky enough to just toss the receipt after getting it and find out a month later their purchase is now out of date. :-(

I was hoping they'd update the English site with V4 info and the same offer, but seeing as that has yet to be done, I guess we won't know until sometime next year what they have planned for sure for the western front. Still keeping my fingers crossed and trying to hold out and fight the urge to not import it somehow... because I know as soon as I do, they'll probably make the same offer in English someday. :-P
