It appears that Sony isn't keen on giving PlayStation Now a proper send-off. But, for what it's worth, the PlayStation now May 2022 games lineup isn't half-bad.
As confirmed by Sony, the "final" set of games coming to PS Now before it merged with PS Plus are Soul Calibur 6, Naruto Shippuden: Ultimate Ninja Storm 4, and Blasphemous. Even if these are not the most popular games, they're fairly above average within their respective niches.
For example, Naruto Shippuden: Ultimate Ninja Storm 4 is the sixth and final installment in the Naruto: Ultimate Ninja Storm series of games which is based on the popular Japanese anime and manga franchise, Naruto. Meanwhile, Soul Calibur 6 is the latest game in the iconic but niche arena fighting game franchise. Finally, if you're not a fan of arena fighters, Sony threw in a 2D action-platformer, Blasphemous.
Sony confirmed in late March that it's merging PS Now and PS Plus into one. A few weeks later, the console manufacturer said it will start rolling out the revamped PS Plus in late May.
