Surprisingly, Sony has announced a very practical extension for the DualShock 4 controller this week, with which programmable buttons can be attached to it. As much as the community is already happy about it, there is also speculation about why now?
With the back button attachment, Sony almost takes the DualShock 4 controller to a pro controller level, even if you have repeatedly emphasized that this field is left to the third-party manufacturers. Also, the time, 6 years after the launch of the PS4 and not even a year before the launch of the PS5, was chosen quite unusually.
Community theories
Now one is already speculating about the reason, with the compatibility with the DualShock 5 controller being pretty high up. If you compare the patent of the DualShock 5 controller with that of the DualShock 4, the back button extension could also be a good fit. Others hope that the feature of the back button extension is already integrated in the DualShock 5 controller and that both controllers are brought to parity.
From a somewhat simpler perspective, the development of the accessories could have taken so long that the launch is only now possible. After all, you have to think about it for a long time, because the interface for accessories like this has been part of the DualShock 4 controller from the beginning.
Other theories go in the direction that the idea for this is also integrated in the DualShock 5 controller, but as part of the touchpad, which may also serve as a display. This would also make the touch field more meaningful.
The Japanese currently only know for themselves what exactly is behind the ambitions of Sony with the back button extension and should be better questioned. You can pre-order the back button extension from Amazon.de.
