It's in dark amethyst Verona. I'm also sad to have missed out on Sorrento goat, it looks really lovely.
Regarding the closure, when I first read your post about concealed magnetic closures, I assume it's just concealed when bag is closed. But the magnets are in direct contact with each other. In that case, it should be fine. Concealed magnets that may be a little weak I imagine would be those behind a layer of leather.
Personally, I like the clean look of the front and would want to be sure that any changes will not create a bulky look or trailing flaps under the magnet closure that may lift up over time. Again, this is just my personal preference. It's worth checking with Marco on specific understanding about how a magnet closure will function and affect the appearance. Might help to even send him some images of closure styles that you have in mind.
E.g. What came to my mind when I think about concealed magnetic closure.

E.g. Trailing strap that tends to lift over time. I dislike this on most satchel style bags, yet I like the overall satchel look. So I was very happy when I discovered the Valerie style which has a clean and neat look.

Interesting indeed! I wonder why it changed. Mine was ordered Nov 2019. Is your square feet the same size as the ones on each side of the top handle?
