From that last photo at the very least it does look like its a fair bit larger than the 30 sitting next to it, given the camera angle of course. Seeing that the 19 is quite a bit more of a hefty bird than others I was a little concerned that Bandai would mess about with the toys final proportions and that it would end up incorrectly sized to around their current line of Valkyrie (25,27,29 in particular) but in that photo it does look like it has a considerable or noticeable size difference happening.
I am super keen to line it up side by side to the Yamato & Arcadia 19 lot and see how much different they really are.
And from the transformation video it does give the impression that its going to be the most complex built Valkyrie from either manufacturer. I guess we'll just have to wait for the final hands on for all the answers.
So anyways the next few days till release will be a long few and to be honest im done with the waiting and just want this thing already. I just hope it lives up to the hope and expectations that people have set for it.
