I don't know when those videos were made but the sandwich is definitely smaller this go around compared to earlier in the year. Slightly disappointed when I got mine the other day. The huge size of the original was part of the appeal. Not to mention they upped the price..Tried one the other week, it was pretty good. Definitely something I'd have again if I had one near by.
However, it was a lot smaller than I thought. All the videos I saw made it seem massive but in real life it was Big Mac sized.
