1) Vf-1S Low Vis or Enigma (i rather the low vis gray scheme, but either way would be nice)
a rerelease of the Low Vis is not gonna happen, the Low Vis colorscheme was a limited release.
2) Thunder Hammer. Can anyone seriously resist this??? U might say you can, but in the end, you would buy it, and you know it!!!
Again, not gonna happen. IIRC the Thunder Hummer is a kitbash, so it's not cannon. I don't think Yamato will make molds for a non-cannon item. BUT, if they were to make it, I too wouldn't be able to resist buying it.
