Much like the PlayStation 3 version of the app, HBO Go on PlayStation 4 is blocked if you're a Comcast Xfinity customer.

Sony announced the much-anticipated arrival of the HBO Go app on PS4 earlier this week. Those who had been hoping the PS4 version would bring a resolution to the problem that has existed on PS3 for a year were sorely disappointed; Comcast continues to prevent its customers from accessing to the streaming service despite competitors like AT&T, Verizon, Time Warner Cable, DirecTV, and many others allowing it.

Comcast has yet to offer a satisfactory answer for the lack of support. As Techdirt notes, customer complaints over the past year--since the PS3 got HBO Go--have been met with a variety of responses from Comcast. Most recently, a company spokesperson chalked the issues up to "business decisions."

"HBO Go availability on PS3 (and some other devices) are business decisions and deal with business terms that have not yet been agreed to between the parties," the spokesperson said on Comcast's forums recently. "Thanks for your continued patience."

When contacted by GameSpot for comment, a Comcast spokesperson declined to offer a timeline for when PS3 or PS4 support would be coming, instead highlighting that HBO's library is available through Xfinity set top boxes and the Xfinity TV Go platform.

PlayStation systems are not the only devices that Comcast has prevented access to HBO Go on. Customers were unable to access the service from Roku devices until this past December, while Amazon Fire TV is still on the blocked list.

GameSpot has contacted Sony for comment and will report back with anything we learn.
