Having heard no answer, I will take a shot : I actually think that EPONs have a good chance to be the future method of distributing video from the "cable" provider to the home. As they are passive, it minimizes the amount of equipment out there. A
May be not... all xPON systems have a wavelength window reserved for DWDM broadcast, that seems more suited to the task.
10-Gigabit Ethernet running multicast IP (probably with some form of packet tagging like MPLS) could more than support all of the video and data needs of a typical cable head-end customer base.
EPON/IEEE 802.3ah is a 1-Gigabit system (actually a 1.25 Gbps but 20% is used by the 8B10B encoding); I haven't seen any spec for a 10-Gig PON; even recently standardized GPON is limited to 2.5 Gbps downlink, 1.25 Gbps uplink.
You might look at alloptic as a equipment provider here http://www.alloptic.com/
