The reason so many franchises of Nintendo continue to sell is because they are used sparingly. Nintendo has put out a lot of mainline and s few spin off Mario games in the past five years. I think they may be alarmed at how games like SM3DW and NSMBU sell decently, but not gangbusters, suggests some burnout.
in short, smart to make a new IP. Every IP was new once, and companies need to have a range of IPs to fall back on.
