35mm Velvia requires around 16MP equivalent according to 
http://clarkvision.com/imagedetail/film.vs.digital.1.html

The late lamented Agfa APX25 has an even higher resolution than Velvia, and 
the dynamic range of film is still higher than digital cameras and not 
subject to "clipping".

I shall stick with film for origination for now - at least its keeping 
properties are well proven!
