The good news is that if you were hoping to make the transition and gaming on the PS Vita a bit more bearable and familiar, you might be pleased to learn that Japanese manufacturer Joetsu Denshi Kogyo has recently announced an accessory for the PS Vita that will add L2 and R2 trigger buttons to the handheld console.
As you can see in the image above, it is basically an attachment that you can clip onto the PS Vita console. It will give the handheld the additional trigger buttons which will make things feel a bit more familiar. Unfortunately it seems that the attachment will only play nice with the PCH-2000 PS Vita model, which is basically the newer version of the PS Vita.
This means that if you have the older model, you’d be out of luck. Its release has been scheduled for late April 2015 in Japan, but no word on pricing or availability stateside for now.
