NOTE - Im just calling it SMG 2 like people say Trico. Even I highly doubt there will be another Mario in space.
Most of your reasons are flawed. Even if they have the resources and all that for a sequel to SMG 2 its still going to take years to perfect whatever it is theyre going to make. The next Zelda I believe has been in development for at least 2 1/2 years. There is not way Ninty would release 2 Mario games so soon and before Zelda. They know how important the Zelda series is.
I also believe its gong to be released this year.
