Which OEM will make the next Nexus Device?

Where Nexus phones being concerned; just like Nexus S and Galaxy Nexus were manufactured by Samsung, the Nexus 4 and Nexus 5 were manufactured by LG. Barring the HTC Nexus One, there seems to be a pattern here. So there is a possibility the next Nexus phone ie Nexus 6/Nexus 5 (2014) won't be from LG. But who could it be? I would like to think Samsung since it would look like 2014 be the year Google and Samsung works together properly unlike before. Or it could be Sony...
