In another attempt to convince gamers that they really do care about their underdog portable, Sony announced Sunday that yet another HD remastered PlayStation 2 compilation is destined for North American PlayStation Vitas. Released in Europe a short time ago, the Ratchet and Clank Collection brings the first three games in the series to the Vita for on-the-go screw collecting goodness. Originally, the game was scheduled to drop tomorrow (the 22nd) on the PlayStation Store, but it got pushed back to the 29th. Details about a potential retail release have not been announced yet, but I wouldn't hold your breath. With the exception of the upcoming Freedom Wars, Sony hasn't been too keen on the idea of retail releases for first-party Vita titles lately.
