I'll try and find out...my guess is that it will be only Calibre 16 in the classical case
I came across a February 27, 2016, posting from the Timezone.com forum, where someone apparently saw all the new models quite early and wrote up some rumors. One item of note is that:
The reference CAR2A10 , CAR2A11 and CAR2A13 will be discontinued : this case will receive only the caliber 16
