Walked into an AD today, while on holiday, to look at the new (and hideous) DSSD. They did not yet have one on display. But I did manage to try on the new SD4000c.
It was sporting a 3.0mm crystal rather than the 2mm that is on the subC's. From this angle, the raised crystal almost looks like a noob or BP!
Also, the lugs, while thinner, do not look symmetric. Could just be the angle, but the left looks thicker than the right:
Also picked up some free catalogues. Woo hoo!
