At the 2010 Summer Wonder Festival in Japan, Roll's prototype figure was shown off alongside Rockman's finished figure. An info card notes the Roll figure coming out in December, though the image is too blurry to make out if there's a price (albeit there probably isn't).
Speaking of "prototypes," a silhouette of another model in the works was also featured, and this is undoubtedly Blues (Proto Man). Though not yet officially revealed, this figure is proposed to release in Winter of 2010 as well. Check out the Dengeki Online gallery at the bottom for a couple more pics.
Rockman figure fans are definitely having unhappy wallets these days.
