When visiting the Dutch Apple site, there isn’t any mention of Netflix for the Netherlands yet. But the site’s Google summary mentions NetFlix already, and so do the meta tags:
<title>Apple - Apple TV - iTunes, Netflix en livewedstrijden op je HD-tv.</title>
<meta name="omni_page" content="Apple TV - What’s On" />
<meta name="Description" content="Met Apple TV kun je je favoriete films en tv-programma's van iTunes en Netflix bekijken, plus livewedstrijden, YouTube-filmpjes en nog veel meer." />
This is definitely good news for all Dutch Apple TV owners! Not only is NetFlix coming to The Netherlands, it will probably also be available on Apple TV right away!
This site: Moreflix.com sums up nicely which movies and series will be available here. I guess the UK and Denmark collection will be similar to ours.
