43rumors exists for three years now and during that time we only had two single Four Thirds related announcements. The [shoplink 17163]Olympus E-5[/shoplink] and the great [shoplink 29677]Samyang 24mm f/1.4 lens (here on eBay)[/shoplink].
I have heard of many other camera prototypes but a part of the E-5 they remained in the hidden labs of Olympus. Of course I have heard about another E-XX(X) model and Olympus already said that they are working on an [shoplink 17163]Olympus E-5[/shoplink] successor too. But it remains a mystery for me if Olympus really will announce the stuff I keep hearing about. As you know the 100mm macro had been deleted from the roadmap and to me it almost looks like Olympus is only waiting for the right moment to merge the two systems in one. That said rumors are still being posted on external websites:
1) A Canadian guy at dpreview forum wrote that “I went to a photo show over the weekend… and spoke to the Olympus rep there… he confirmed a E-7 is definitely coming (which is known), but also suggested that there is much pressure from Japan for Olympus to build a E-720 type camera given that many people still want something between the EM5 and E-5…”
2) And the well (oly) connected Damian McGilliCuddy keeps posting mysterious E-X or E-XXX messages -> He started to post this kind of messages back in February 2012.
As I already told you, I think Olympus goal is to release a “professional” E-M Micro Four Thirds camera that provides full AF support for the great Four Thirds lens system. Once they have done that the only remaining argument for classic DSLR development remains the Optical Viewfinder. But I don’t think this will be a reason enough to keep the DSRL segment alive…
