More PlayStation ports of great games sounds good to me.
The lovely 2D action-RPG Dust: An Elysian Tailis coming soon to PlayStation 4, while the hilarious fencing game Nidhoggis headed to both PS4 and PS Vita, complete with Cross-Buy.
The former title should look especially nice running at 1080p and 60 frames per second. As for Nidhogg, its online multiplayer is cross-system (PS4 vs. Vita) and two people can compete against each other using a single Vita, too. Just don't get overly worked up and drop the system.
