After the $500 instant rebate, the Pentax K-5 IIs DSLR camera is now listed as discontinued at B&H.
The Mamiya RZ67 Pro II medium format camera is also listed as discontinued:
I also received some information that the Mamiya 7II medium format camera is also already discontinued (not listed at B&H, still in stock at Adorama).
Mamiya is rumored to release a new medium format digital rangefinder camera in 2015.
