[public-lod2] Official DBpedia Live Release

Quick question: on the basis of point 6, will resources in the main
http://dbpedia.org/ namespace soon reflect the latest changes from
DBpedia Live? Presumably at this point the separate live.dbpedia
SPARQL endpoint would become redundant?
Also, and not wanting to poor petrol on the flames of any current
debates, but, the links at  under "20 Most Recently Updated
Entities" point to the dbpedia /page/ URIs, not the /resource/ URIs.
I'm guessing this isn't the intended behaviour ;)
