Sony has confirmed that it is continuing to work on the PlayStation Plus Edition of PS4-exclusive DriveClub.

The comments come after Sony Computer Entertainment Europe boss Jim Ryan recently declined to confirm whether the racer's long-delayed lite version would still launch at all.

"We are continually working on improving the server capacity to enable us to launch the PS Plus Edition as quickly as possible," a Sony spokesperson told Eurogamer.

"Although currently we do not have an update regarding the timing for the launch."

DriveClub suffered from a disastrous release. Delayed, then dropped onto Sony's servers in a dire state, the title has slowly been improved by a long series of patches and free DLC.

Server problems scuppered Sony's original plans to offer the PS Plus Edition alongside the game's full retail launch - which at one point was due to happen alongside the PS4 itself.

The PS Plus Edition was announced as being "temporarily held back" in October last year. Plus subscribers have been left waiting for more news ever since.
