Those relatively small flat screens used in the EBU tests may be very trendy, but any self-respecting HD geek would only contemplate a picture with at least a 2.5 meter base.
Also, consider that some "live" events might be retransmitted in digital theaters on a cinema-sized screen.
I understand it would have been difficult to set up a demo with three 10 meters wide screens, but at least 2 x 2.5 m above one another could have been considered.
Big screens would be more revealing of resolution deficiencies, and the conclusions would have offered some security margins when applied to smaller ones.
I don't think the choice of the more appropriate standard should be based on the present market trends, especially in an industry where things can change so quickly.
Watching a 1.27 m screen (diagonal), even in high definition, does not fundamuntally change the TV experience. With a 2.5 m screen (width), it really begins to fell like you're at the movies.
A sizeable fraction of the early HD adopters have opted for a big picture (which means front projectors at the moment), and EBU should not make a choice that would clearly expose limitations in such viewing conditions.
Perhaps the final conclusions would not be very different, but at least the test should be made.
