Blue one looks great.
These are going to be popular:

Annoyingly, all of these are still negative displays, which IMO is a poor choice given how small the inset display is. It's already possible to buy 3rd party metal cases and mod one of the positive display versions, although those cases tend to be a bit more of a blatant Royal Oak homage, rather than true to the original Casio case design.
I've got one of the original series and I will continue to hold off on getting another variant until there are more positive display options. I think that silver dial variant would be pretty good with a positive display. If I didn't already have the one I have (and admittedly almost never wear because of the annoyingly hard to read negative display), I'd be very tempted by the blue one.

Oh those do look nice! Particularly the blue and the silver options. Tempting...
