On the latest Command Center stream on Twitch (via IGN), creative director Matt Higby talked about bringing the game up to Sony Computer Entertainment America's headquarters to show it off recently. He talked about the strides that have been made in recent months that allowed the game to be demonstrated with dozens of players playing on Indar (one of the game's three continents), adding, "We were able to demonstrate all that stuff on the PS4 running at a smooth framerate, running at 1080, so we're very happy with the progress that's being made on that."
Higby described the PS4 version as "really good" and said the biggest focus now is on optimization--presumably ensuring that framerate remains "smooth," as he describes it--and designing a user interface that works well as the game transitions from PC to console.
Plans for the game's release were discussed with Sony, but Higby gave no indication as to when that might be. He did, however, mention when players would be able to start going hands-on with the game, saying, "We will be at E3."
As E3 is a press-only event, that won't be chance for the public to play the PS4 version, but Higby said players could expect to "start seeing some hands-on videos of the game in action." Fans will get the opportunity to play the game for themselves not long after, as Higby said the game will also be at the MLG Championship Anaheim event that runs from June 20-22.
When it was announced at E3 last year, the PlayStation 4 version of Planetside 2 was expected to be available by the end of 2013. It was delayed in October until an "early 2014" release, which obviously hasn't proven to be the case. Whenever it is released, the game will, like its PC counterpart, be free-to-play.
