I don't think there ever was a deal was there? It certainly didn't stop them and a 3 year contract on a franchise that takes 3-4 years to make would, imo, be pointless.
I suspect that its just because Nintendo has had the 3 best selling platforms in Japan for a long time now. Ds, Wii, and 3DS. Its a shame more companies cant put their bias aside and put their AAA quality titles on their platforms.
