I wonder if Nintendo will have anything that rivals the production values, polish and technical wizardry of The Last of Us, Crysis 3 and God of War: Ascension.
Eventually they should, easily. Ninty has been working and training for the switch over to HD for ages now, and last time their teams were on fair footing hardware wise Nintendo's games were always up there with the best from any other platform in those aspects. They haven't got worse at developing since then, their first party Wii games were fantastic, and a new 3D mario, Zelda, or retro game (and MonolithSoft's new game) should be at least as good looking and polished as those games, and quite possibly look better due to the more powerful hardware.
I mean, perhaps not launch software, but Nintendo's best studio's are still elite and they will have the superior guns to work with for a year before anything mroe capable comes to the console scene, and the style of many of nintendo's games (whimsical, stylized) will possibly still allow them to have some of the most beautiful games of the entire generation, even accounting for PS4/720, who won't be nearly as noticiably visually above Wii-U as PS360 are above Wii, and even so the galaxy games, xenoblade and Skyward Sword are still some of my personal favorite visual experiences of the gen (I have a PS3 and many of those games are pretty too, but there is alot to be said for great art direction and style, which Nintendo nails even on lesser hardware.
As for launch software... I could see Pikmen 3 being super beautiful, but if it started off a Wii title it may not be quite up there. If Retro has been developing a new Metroid Prime or Star Tropics like I suspect those could easily match the best looking games likely to show up on other platforms... Also a new IP could be staggering if one of Nintendo's studios has been covertly working on one for a long time.
