I would be really surprised if NOVA 3 was freemium. Modern Combat 3 was not and it was released when they already started their freemium experiment. Gameloft has already apologized for DH3 and made it clear that they will continue to release premium titles; as well as paymium and freemium, also stating that they have learned valuable lessons. NOVA is arguably one of their most popular games; with the DH3 reception, I would be downright shocked. I wouldn't doubt the possibility of freemium gambles with some of the upcoming titles; such as the Avengers, Men in Black III, The Dark Knight Rises, The Amazing Spider-Man, Assassin's Creed or My Little Pony. Gameloft has stated that they intend to release as many titles as last year; they releases 18 the second half of the year. Also, there are the games to be released with the unreal engine; as far as I recall they weren't all cancelled.
Also don't know which titles will be on iOS yet.
