Indeed it is, actually, it already sorta works. Yesterday the app for it appeared in the Dutch PSN store, I could get a 7-day trial subscription. The app was later removed again and never appeared on my homescreen but I can play PS Now games when I select them thru the PSN store since the app can’t be downloaded anymore it’s still visible with all the PS3 games that it supports and selecting one of those will start it. Also the PS Now beta app now seems to work with the 7-day trial as well…

So it’s up and running but they probably still wanted to change certain things. One thing I’ve noticed is that my console is all in English (I hate computer/console stuff and games in Dutch) but the regular PS Now app showed me Dutch text everywhere, the beta app still shows English. So they might have a few kinks to solve yet with the diff languages
