Mine seems fine Rob...
And the size differences aren't even well represented in the images that were out. Having one in-hand now, they're pretty different. Definitely different width, especially at the front, the size of the weapons are all scaled down, the engines, etc. Everything is smaller. Much more noticeable in person. That was one reason I was geeked for this at Toy Fair... Just seeing it in person I knew it was pretty good now.
Hasbro knocked it out of the park too, in every respect. From rivet/bolt holes, to recessed panel lines, to the warnings in aurabesh, to the tiny (and I mean tiny, but accurate) harpoon gun (I always considered it a light laser too). They really did a bang-up job. Even an escape hatch sculpted into the roof of the cockpit for the gunner, incase the pilot's incapasitated on a crash... Super detail there (not functional of course, but super detail regardless).
Even the landing skid has little shock/pistons sculpted into it. It's one of the most detailed ships I think Hasbro has ever done.
