There's no way they throw Mario & Zelda out at the same time. They'd compete with one another for sales, and they're two games they rely on to boost system sales, so they need to be spread out. But beyond that, one of the traditional failings of Nintendo consoles has been that 3rd party games don't sell well; they abandoned the Wii U quickly because they didn't like what they saw at launch. If both Mario & Zelda are out there day one, nobody's buying 3rd party stuff as their second game. Expect to see Mario hit in September to kick off holiday season sales.
I do agree they'll have something new that shows off the system's capabilities in a unique way, like Nintendo Land & Wii Sports before it.
I'm afraid even September would be too optimistic, if Mario isn't launch, I don't think it's gonna be out until November/December.
