I've been noticing something strange about Jazz... it's very subtle, but I'll try to explain it.
He seems to have a different head everytime we see him, and I think the version of him with "eyes" has been scrapped in favour of keeping his visor down at all times.
Look at this collage here. On the top right is a segment of the "concept art" that was leaked on eBay that day, along with the art for just about every other movie character. To the left of the auction pic is an image of what is labelled as his "Standard Mode" head, taken from the cover of one of those "I Can Read" books and under the auction pic is the boxart from the toy, labelled "Battle Mode". If you look closely to the section taken from the concept art auction, you can see that both of these match up the way they are supposed to.
The new image on the left is of the Jazz display that Omegawrath found. Notice that the head there doesn't quite match the other two. For example, the visor is pointy at the end of the newer pic, where the "Battle Mode" on the toy has a rounded visor. The "ears" on the "Battle Mode" are much larger and "fuller", so it's pretty clear that the head seen in the new pic of the toy display is
not his battle mode. The problem is, it doesn't seem to be his "Standard Mode" either...
...or is it?
Take a look again at the new toy display pic, and the old cover of the "I Can Read" book with the visor-less Jazz:
It's the exact same stock photo. Same pose. Same everything - the only thing that makes it difficult to see is the angle that the new pic was taken. But for me, it's clear that this is the exact same stock photo, the only difference is that Jazz has his visor now... why change it?
So does that mean that Jazz will have his visor for the whole movie? I have no idea... but it is weird. One way to find out would be to get a good close-up of the Jazz figure. If it has the rounded visors and larger "mouth vents" of the labelled "Battle Mode" that won't tell us much. But if it has the pointy visor, with the more straight mouth thing, then I'll start thinking that maybe Jazz's head was changed in favour of a visor instead of "eyes".
