Astray Blue Frame Third is armed with huge swords similar to that of Strike Noir, while Strike E is just Strike Noir in white, with shield.
At the moment, I only see Gundam Astray Blue Frame Third, and Hyperion G being 'new' (their principle designs are not new anymore) designs, while most of the other MSs are just color variation of their original designs, which is really quite uncreative :( Also, in a way, I feel like each of the SEED series in the past are sending their representatives to participate in this series ^^;
SEED - Cgue,
SEED MSV - Gundam Astray,
SEED Destiny - Gouf Ignited, and
SEED Stargazer - Strike E, Civilian Astray DSSD Custom, Kerberos BuCUE Hound.

This sure makes Bandai to able to release the models of these mecha easier, and not to mention cost-saving as well. Except for Astray Blue Frame Third and Hyperion G, they just need to design new stickers, box cover and construction manual, and a 'new' model is out. As a result, five of the mecha mentioned above are going to get their Gunpla treatment next year: Lukas's Strike E + IWSP will be released as a MG, while the others: Rudolf's Gouf Ignited, Xist's CGUE, Alec's Kerberos BuCUE Hound, and Hyperion G will be in 1/144 HG format.
With three Gundam Double O around, can you still pick up the enthusiasm for SEED and go for these 'new' models?
Definitely not for me XD
