I'm not saying it won't happen, but I don't think that what could amount to an HD port (not literally of course) of Versus from the PS3 to the PS4 would really be all that helpful. Whether their recent titles deserved it or not, Square is generally known for pushing hardware. A PS3 port wouldn't do that without rebuilding large chunks of it from the ground up. And I don't really see the value in doing that.
