Sony will be ending production for physical PlayStation Vita games next year. According to an e-mail sent to developers, which was obtained by Kotaku
and later confirmed by a Sony spokesperson, the American and European branches of Sony will cease to produce any more Vita cartridges beyond the end of fiscal year 2018. New digital titles will continue to be released on the platform.
Developers have been asked to make sure that they submit all product code requests for physical carts by June 28th. The deadline for final purchase orders is February 15th, 2019. The fiscal year ends on March 31st, 2019 — after this point there will be no more Vita carts in North America and Europe.
Beyond this date, developers will still be able to release their Vita titles in digital format. Several of these developers have rushed to assure their fans on Twitter that their games will still continue to appear on the platform in some form.
While it hasn't been confirmed, we assume that players in Asia will still get physical games in the future. Of course, Sony's handheld device is much more popular in this region where is still consistent support for the device from developers, publishers and players alike.
