In fact Sony, trying to keep their foot in the door with tape machines,
(still there primary business) has announced (publicly stated) that at
NAB they will show a prototype of a new uncompressed HDTV vtr.  This
replaces their open reel 1" machine that uses tape that costs
$1,000.00/HR.  When the HDTV Sandards were announced at this time a year
ago Sony found that they did not have a Modern VTR for Post Production. 
Instead they had spent the effort on a 7 to 1 compressed format for
field recording that fits on the back of Camcorder sized like a
Digi-Beta.

This recorder will record the current HDTV digital standard of 1920 x
1080 at 60(or 59.94) interlaced fields per second.  Also it was
announced  that it would record full bandwidth RGB (no transcoding) at
1920 x 1080 24 Frames per second PROGRESSIVE.  This is because when you
do the math you find that the data rate is the same for the two
formats.  (Ron Martin--are you listening?) Yes, Sony recording at 24
Frames progressive.  Bet you it will also record 720 progressive too. 
They also announced they are going to make a 24 Frame progressive Field
camera for "Cinema" shooting for going back to film for distribution. 
The VTR is based on their "D2" transport---OH NO!!!!!!!

Only catch is that the VTR will not be available til "Some time in
1999"  In the mean time D5 is gaining a strong foothold in the market.
