In an Interview with techradar a Sony spokesman says:

"We are aware that Field Emission Technologies is in negotiation with Pioneer regarding mass-production of field emission displays, however this does not have any implications for Sony's existing relationship with FET."

FET is aiming to produce 10,000 26-inch FED panels each year at the plant in Kagoshima (Japan).

These will be for medical & broadcasting use 1st, but you can expect 60-inch consumer TVs later on...

What is FED?

The nano-Spindt FED (Field Emission Display) is a kind of FED that reproduces images using an array of nanocone emitters to excite phosphors.

Taking advantage of highly efficient self-emissive phosphors combined with a line-sequential impulse drive system, this display delivers the visual performance required of a next-gen flat panel display, including a wide viewing angle, outstanding contrast with true black reproduction & lifelike color and last but not least; no-blur display of quickly moving images.
