No larger scans available for these two at the moment.
At least 6 or 7 runners as observed from the picture. But even without closer scrutiny, it's pretty easy to spot that Bandai has left many openings for the upgrade to Gundam X Divider. ^^
A total of 4 body parts for the beam rifle/shield is spotted. Seems like it'll not be transformable. ^^;
Also, this is a new HG series as shown in the magazine scans, and Gundam X will the first release, followed by God Gundam and Double Zeta Gundam, meaning the later is excluded from the HGUC series?
April release, 1,890 Yen (inclusive of tax).
* HG 1/144 God Gundam - May release, price TBA.
* HG 1/144 Double Zeta Gundam - June release, price TBA.
