3dstore's screenshot from the product page is why I am a bit sceptical to the new 1200x main product image size. Unless images can be dynamic in size and be scaled down on smaller screens, they are already too big. Imagine what a forced 1200 width is going to look like on this person's screen.

Yes it is nice to be able to see details, but that ought to be available on a second click/zoom, whereas that first impression on a product page should be an opportunity to see the whole image easily.
