This is ridiculous. You need a well adapted bandwith (less than double indeed but still adapted to the raw datastream), but there's nothing in the MPEG2 that prohibits encoding in 1080p50 and/or1080p60. More so, MPEG2 will probably be a preferred format for 1080p, because codecs without temporal efficiency would eat up too much bandwith.

1080p50 or 1080p60 in MPEG2 with 6 (or 12) frame GOP and a bandwith of 50-100Mbps would look very, very good indeed.

On the EX1 in HQ 1080i mode each field would be 1920x540, and in 1080p mode would be 1920x1080. In 720p60 mode the still-frame resolution would be the same as a JVC HDV camera, but with slightly more bandwidth per frame.

After shooting some footage on the EX1 this weekend I'm hungry for even higher resolution: when can I get 4K at 60 fps? ;-)
