Have a look at the video at the above link. Reggie's talking about the Wii U yada yada Geoff Keighley is there yada yada there are a couple of glamourous looking women there yada yada but pay attention to what the lady on the left says.

She asks if Mario Bros is going to be on the system! Someone watching at Nintendo HQ must've then went "Hmm..." while stroking their chin and decided "Right! Develop a new 2D Mario!"

That's my made up story and I'm sticking to it!
