The concern about old/proprietary data formats is a real concern. 
The problem with proprietary data formats is becoming worse rather 
than better, with new digital camera systems sourcing vendor-specific 
formats and a trend to store all original source elements.  When the 
software that understands these formats and the original source 
elements expires, then the digital data becomes distressed.

Everyone agrees with this.  Active curation and management is 
required, even it if can be automated.  You can't just put the digital 
media in a dry cave and hope for the best.
