However, PSP titles and supported minis will be playable on the handheld device, while PSOne classics will be available at a later date, explained Sony.
"PlayStation does not have plans to make PS Vita compatible with PS3 or PS2 titles at this point," Sony confirmed on the PlayStation Blog.
"Users can play supported digital PSP titles and supported minis," it continued. "In regard to PSone classics titles, we will announce further details when they are ready."
Sony recently confirmed pricing for first-party downloadable titles on Vita, and has said that retail titles purchased over Sony Entertainment Network will be given a discount.
PlayStation Vita will arrive in North America and Europe on February 22.
