Sony has added the option to rent certain games from the US Playstation Store, though the links don't appear to be functioning yet.

The interface was spotted last night by MP1st and PSN Stores (via VG247 ), leading to speculation that a non-public test is taking place ahead of PlayStation Now's North American release later this year.As you can see, options exist for renting games for either one, seven, or 30 days. Regarding the "free" pricing, that's probably just a placeholder until the service goes live. Seeing as this is very likely tied into PlayStation Now, it's possible the potential prices for the service spotted earlier this week will apply.There's still no firm information on when Europeans will be seeing PlayStation Now, though the best guess is 2015 at the earliest as Sony has admitted problems with broadband strength in Europe . It's expected to roll out in North America later this year; for ideas on what to expect, check out our hands-on impressions PlayStation Now will recommend an internet connection speed of 5Mb/s to ensure a "good experience", according to Sony.
