Digipixelpop talked with a Leica rep at the 2014 NAB show and was told that the next Leica S will be announced at Photokina (September) with a new 40-50MP CMOS sensor and 4k video:

"Talking with a Leica rep at NAB in Las Vegas, I was told that Leica will be announcing a new Leica S camera with a 40-50 megapixel CMOS sensor at this year’s Photokina expo in Germany. The CMOS sensor is expected, as is the resolution bump, but what really surprised me was that there they were also adding video… 4K video."

This should not be a surprise since both Haselblad and PhaseOne announced new medium format cameras with CMOS sensors and 4k video seems to be the next big thing in video.

Update: the upcoming Pentax 645z medium format camera is also rumored to have 4k video.
