They need to drop the price significantly to appeal to kids/family market (where parents make the call on which system to get). Right now they are getting killed by the cheaper PS3/360 for that market.
I don't think LEGO City or even Wind Waker HD (a game that couldn't sell GameCubes even when it was new 10 years ago) will do much of anything for Wii U hardware sales.
Nor do I think 3D Mario is a huge system seller where 2D Mario was not, even on the 3DS, NSMB2 has outsold Mario 3D Land already I think.
Mario Kart and Wii Sports U is probably what they'll push hardest this fall, even though I think Wii Sports' time has come and gone, it can't do worse than Nintendo Land (or can it?). Despite what people say I do think Nintendo was banking heavily on Nintendo Land to be a heavy hitter but I think the mini-game formula has grown stale for many people.
They should try marketing the crap out of Wonderful 101 to kids and creating NFC figurines for that game. They need something new to break out.
