I jumped in and installed. Seems to work fine. Native Access ound more updates (19) than service center (15) although NI says that some products currently still only update via service center.
Update procedure is super nice using an [Update All] button and than it downloads and updates in parallel.
Installation of new DAWs will be heaps easier. I had to rebuild one machine from scratch recently and just applying all updates to K10 ultimate was a nightmare (took ages!!). Now it's click to select what you want and off it goes, installing the latest version by itself ... tried it on a machine where no NI was yet present and it worked fine.
