More simply, there's still a long way to go until Wikidata imports all the data contained in Wikipedia infoboxes (or equivalent data from other sources), let alone the rest.

Why would you want to import all the data contained inĀ  Wikipedia info boxes? I would rather aim for the oposite, i.e. Infobox being built from data in Wikidata. Simply because with Wikidata it is easier to capture where the data is coming from (through the references and qualifiers) than with Wikipedia info boxes.
