They really don't look that much different on the whole, yeah i can see that peaches dress is more "rounded" (has divets in it on the prototype), and maybe that gold stuff on her dress (which looks different in the prototype but could be lighting) but overall it looks about the same overall. Maybe a bit less on some but nothing like as bad as i was expecting when i hear people say they look "utterly awesome now and I'm canceling my pre-orders"
The swords are bent in one pic but that seems odd to me, as if they got whacked in transport, I imagine they bend back if a bit of pressure is applied (and for safety reasons i imagine they can't be fully "solid" and need a bit of bend, to stop them from snapping).
But bending it back would stop them from making the point kotaku wanted to make
A lot of the "omg its worse" does seem to come from the lighting as far as I can see it, with a pinch of exaggeration becuase the lighting in the new shots is a bit on the awful side, mainly becuase its not "white" light, its yellow.
The link stand thing is a bit disappointing but at the same time i was thinking that the link one looked a bit breakable or snappable on the prototype so i imagine it was for toughing up reasons.
Experiment for someone, take the pictures, put it up on your site with a article about how they look better than the prototypes, see what people say. See how much of the "they look worse" is people reading the article then looking at the pictures to confirm the article rather than making their own decision.
And before you mean, its a confirmed issue with how our brains work, hence why people handed McDonalds to organic food lovers and got told it was great, because they said it was organic when they handed it over (and hid the boxes obviously).
[EDIT] If you have a look at hte picture with all hte marth ones in teh background, you can see that the other marths swords seem straight, a more cynical person like myself would have something to say about this.. something like they choose the one bent one out of the pack to make a point. But of course that's just silly cause its not like kotaku make their money from click bait at all so they would never exaggerate something for more vie...oh wait
