Snakas has published his round up of the latest issue of Dengeki Hobby Magazine which you can read here in Japanese. The issue contains pretty much the same contents as the latest issue of Figure King including Transformers Encore Metroplex, Suntory Limited coffee boss campaign, Transformers Henkei, Transformers Alternity and the Transformers Marvel Crossovers.
The Henkei article confirmed that Streak is slightly recoloured from the Western release, and that Galvatron and Ironhide will be released in November in Japan.
The Alternity GT-R figure is listed as going on sale in January 2009 for 4,725 yen which is the latest source saying that the figure has slipped from a November 2008 release, back to 2009. Once again, the profile and character name were not published.
Finally, more information and images were published on the Chara-Hobby 2008 exclusive Transformers Henkei Wildrider.
