In a recent interview with Dpreview, Olympus representative confirmed that the company is committed to MFT and that "full-frame isn't for everybody" - exactly what they said back in February:
I think one big thing with Micro Four Thirds is that we're using one single format. So if you buy a new lens in the future, or replace your camera, you don't need to switch formats. This is a great benefit, The second thing is that there is a very strong mindset in the US that bigger is better. Full-frame is better. But the size of the sensor does not determine the cost of the product, or the quality of the picture.
If someone really needs a bigger sensor because they're shooting in really dark conditions, or they need to make really big prints, then full-frame is a better choice. But if someone finds value in a smaller package, not just the camera but also lenses, then [our OM-D cameras] will be better.
Between the horrible financial reports, premiums prices, Sony selling their $760 million stake in Olympus, the upcoming price increase and the rumors about Olympus exiting the camera market, I am not really clear what strategy Olympus will pursue in order to survive only with the MFT format.
