Yeah hopefully it will be available by then! On the downside, they are charging quite a bit for the next clasp if I remember correctly, so likely the price will go up somewhat when they do release the new clasp.
Yeah the clasp is the most common complaint about the 556. And yes, Sinn has recently introduced a new clasp which is physically a little bigger but has on-the-fly (toolless) micro-adjustment. However, it's only available for some Sinn models so far, and the 556 is not yet one of them. You could consider waiting, but we have no specific timeline.

The other complaint I hear is that the hands are stubby/too short. That has never bothered me personally. I think the large 3, 6, 9, 12 numerals on the A version help and the issue is more noticeable on the "i" versions of the watch.
Bracelet aside, I'm wearing that very watch as I type this. I've had it for almost 2 full years and still absolutely love it. I got mine on the black leather strap with red stitching, but just switched that up this past weekend to a 1-pass Nato-style strap https://www.watchcrunch.com/mutnat/posts/new-strap-day-10-397693.
The watch is great. Rugged, keeps great time (averaging about +2 or +3 seconds per day most days), looks fantastic (IMHO). And despite the potential downside of AR coating on the outside of the crystal, its presence really makes the crystal disappear. It's very effective.
I'd definitely recommend it! Did you have any more specific questions or concerns you wanted to ask about?
