A good source told us that while It is true that Samsung is developing a NX Full Frame system the first camera will be available in 2014 only. And if the info is correct than 2014 sounds like the year where plenty of manufacturers will launch their FF mirrorless system. Sony is rumored to launch a new NEX-9 with 24 MPX sensor along three new Zeiss primes in June 2014. Fuji may will follow with a new FF X system in late 2014.
Nikon and Canon instead will keep focusing on the launch of ultra cheap FF DSRL and that may be a serious challenge for all future FF mirrorless systems!
