It is going to be interesting to see whether XDCAM HD has much of a life  
span and ever reach the lofty promises that Sony made about it.  Even  
XDCAM HD's disc based media might look quaint in 18 months.  I'm sure  
the Xpresscard memory sticks will become ubiquitous in that time span. 
 
Memory cards and direct recording to HDDs seem to e the biggest threat  
but if XDCAM HD is to continue will albeit an updated codec and increase  
in bit-rate is always necessary. 
 
I can't see too much requirement for greater than HD or 2k recording at  
least for broadcast media so I would assume the next development to eat  
into the bandwidth reserve will be enhanced colour resolution and depth  
caused by much improved latitude from the camera front-end.  So son of  
XDCAM would need 100++ Mbps. 
 
Who would be an owner operator at this time?  Very costly if you back  
the wrong horse...
