In industry, that may be so (I seem to recall one of the Star Wars prequels being the first feature movie done entirely with digital cameras). For end-user video cameras (handicams, or whatnot), we've been storing to magnetic tape for a good bit longer though.
Being digital doesn't mean using solid state storage. Magnetic tape is probably still the most used medium for digital video cameras. For example, Betacam SX is still used.
