Sony has announced that worldwide sales for the PlayStation 4 have topped 18.5 million, with 4.1 million of those sales occurring during the holiday shopping season from late November to early January. The company also revealed 81.8 million PS4 games have been sold overall, and that PlayStation Plus subscribers now top 10.9 million.

Speaking of subscription services, Sony is planning to launch PlayStation Now subscriptions in the United States and Canada next week, on January 13. The service, initially available for the PlayStation 4, will allow you to stream as many PS3 games as you like without having to download or install anything.

Subscriptions will be available for $19.99 per month, or $44.99 for three months. The rental service, which has been available for several months, will continue to be available, allowing users to rent single games if they don't want to shell out for unlimited access.

PlayStation Now currently contains over 100 PS3 titles, which may not be the full library of nearly 800 games, but you'll find many of your favorite titles are available. Supported games range from exclusives like God of War: Ascension and Killzone 3, to wide releases like Dead Space 3, Saints Row IV and Dirt 3.
