Real or not this is the very last rumor floating around the chines XITEK forum. While I am pretty sure the NEX-F3 rumor the rest could be a “fake” guess. Anyway, I hope the rumor is real because I like that rumored Full Frame NEX-9
Sony NEX roadmap:
NEX the F3, C3, an upgraded version, 2012 (March)
NEX 5G, 18.3 million pixels, as the upgrade version of 5N 2012 (September)
Full Frame NEX in late 2013.
