Promised PS4 features such as suspend/resume and the ability to invite friends to take over gameplay remotely are being worked on at Sony, according to the company's head of worldwide studios, Shuhei Yoshida.
First announced in February 2013, the resume and suspend feature is expected to radically reduce the loading time between players and their content by keeping the console in a low power state while preserving game sessions.
"The time it takes today to boot a console and load a saved game will be a thing of the past," according to Sony.
However, speaking to Kotaku recently, Yoshida said the feature, among others, is "not ready yet".
"Our team has been working on it," he said. "There are some things that we announced in February of last year that were not planned for the launch timeframe."
When asked when they would be ready, Yoshida admitted that he had not yet been given a specific timeframe.
"I am asking the same question to my tech team every other week. Because every day I get reminded by lots of people: 'Where is this? Where is that?' It's a great reminder for me."
At E3 Sony announced that Far Cry 4 owners would be able to invite friends to play co-op with them, even if their partner does not have a copy of the game. PlayStation Europe president Jim Ryan told CVG in an E3 interview that the feature is "the first manifestation" of an existing idea for the console and is "envisaged as a platform level feature".
