Supposedly a RS Trilogy was already completed for Xbox and never released, they already did a test port of RS3 for Wii, and its already been revealed that they have been working on a Wii version of Rogue Squadron when we found out that they transferred the development over to Whitehaven LLC. So I would be surprised if RS didn't make its way to Wii too.
We also know that they were working on something that could've been Pilot Wings, and we also know that they atleast pitched Icarus over to Nintendo. Its also possible that they could be working on a new StarFox game as that would be right up their alley.
