Reader akum6n has this to say:
"There are two methods of release for these figures. First, they were given out to participants at Saikyou V Jump Festa at Makuhari Messe (in Tokyo) on 7/21 and at Intex (in Osaka) on 7/28. These are probably the ones showing up on auction sites now. Second, the figures will also be given out through coupons in the September issue of Saikyou Jump (for Jidam) and October issue of V Jump (for Pirazon) that can be redeemed for the figures. Both issues became available last month. So, I suspect we will be able to pick these up eventually without paying the premium prices attached to those on eBay."
...if you have a much cheaper lead on these, let us know in the comments or email us! We're interested! (Well, if they're cheap or if you trade.)
