:::::There have been various mentions in the SignPost for example of which one of the latest ones is Wikipedia:Wikipedia Signpost/2013-02-04/Technology report. 
 :::::About Roy Chaplin: It seems no articles about him exist in other Wikipedias and no-one has yet created a page on Wikidata for him. Feel free to do that. 
 :::::About infoboxes: Template designers and maintainers can work on moving their templates to Wikidata if they wish so as soon as the necessary data is in Wikidata and the code is written to make it possible. That'll still take a bit. Infoboxes will not be necessary. Infoboxes with Wikidata will not show up automatically unlike the language links. People will have to go and set it up just like they're doing it already now. One of the key differences is that they'll be able to make use of a lot more data that has been collected by more people in more languages.
