Celebrating the 10 anniversary of Gundam Seed (and the rerelease of the anime on Blu-ray) Bandai has released their 'remastered' versions of their great HG kits from years gone by.  Calamity Gundam is identical to the initial release but now comes in colors matching the Blu-ray anime, marking stickers, and an extra part that lets you attach Calamity Gundam to an action base 2 (sold separately).
