I don't think that would be much of an issue. As it only seems to be top heavy it is in its current resin form. The ABS pre-prodution version should be much lighter with much more thought put into the SV-51's ability to stand on its own. I'm just wondering how there going to make the periscope work without being so fragile.
I can only imagine fighter mode of this monstrosity (38cm/15in). AWESOME!!!
So, if the SV-51 is coming. Then, surely, the VF-11, YF-21, and the VF-0D should be coming as well. Since it is stated (by Graham) that Yamato IS truly devoted to the Macross license. Who knows, maybe even the VF-22S could make an appearance in the distant future. And as a far fetch, I'd even speculate, the Ghost from Macross Plus.
It's a GREAT TIME TO BE A MACROSS FAN, now that we have an actual toy producer on our side.
