I don't think games like X and Bayonetta 2 will be made by Nintendo in the future. Those games were made with the intention that the Wii U was going to be a successful platform right now and it's nowhere close to that. They'll bomb on the Wii U and Nintendo will wash their hands of them. Also series' like Pikmin are probably going on (another) long hiatus.
I think Zelda will also not be the realistic style of that trailer, they are going to go with something more cartoony like in the end (like Skyward Sword).
