Based on the Mario leak, Nintendo had a deal with Sony for a Mario movie which was completed. Avi Arad, the producer even met with Iwata and Miyamoto apparently and they celebrated by having cake or something per the leaked emails, lol.
So that still may be coming. Movies aren't made in a few weeks, it just may take a while for the script to be finished first and then CG movies have usually 2-3 years required for the animation.
