Product descriptions come from the manufacturers and this is clearly a generic product - so totally inconsequencial.
However, its a very, very safe bet that Canon will field a 5DIV sooner or later due to the overall succes of the "5D" line following the original 5D and later the 5DII - the best selling FF camera ever. Canon will want to associate future products with that succes story as they did with the 5DIII.
