According to Olympus Japan (via Photo Rumors), they seem to have suggested that the demand for their cameras has exceeded the supply, hence the delay. “For February 26, 2016 launch of the “Micro Four Thirds System standard,” mirror-less single-lens camera that conforms to the “OLYMPUS PEN-F”, because we have received your reservation in a very large number of customers, some of our customers the, after the release, I might get time to deliver the product.”
Granted the translation is a bit off, but basically the message indicates that the camera’s release has been delayed, although unfortunately Olympus did not mention exactly by how long. This means that for all we know, the camera could be released in April, May, or maybe even June, but hopefully the delay won’t be too long.
Olympus also notes that to some of their customers who have already made reservations, it seems that despite that your camera might still not make it on time. As it stands, Amazon which had the camera in stock previously, has now listed the device as temporarily out of stock, but do check back with us soon for more updates.
