It is easy really

-Make small games over big games.
This allows more different types of games to be made and all going to different audiences. It also has a bigger chance to have more hits. Also not all games have to be mini game collection or 3d games. Throw in some 2d games. Have everything is basically what I am saying. Also imagine if all the nintendoland games were full games O.O

-Do not make tablet controller required
I should be able to use any controller I desire, If I wish to play a 2d games nes style than let me do it. Also games should allow as many control options as possible, That way everyone can be happy. Hey you can sell a wii u without a tablet and now we got a much cheaper system

-Create a user account system like Apple! I want to play my virtual console games on my 3DS ,wii and wii u without paying for it 3 times.

-Also release pikmin 3! This is the most important one!

Edit: Also screw 3rd parties. If they don't want to make games for their consoles. Reward those who wanted to and succeded 

So essentially make a Nintendo-fied Xbox Live Arcade? 

I disagree with #1, #3, and #5.
#1 - Nintendo does not need boring Hollywood people to be in their ads. The "Wii Would Like To Play" guys from the early Nintendo Wii commercials were perfect, and they had no celebrities involved. They need something recognizable like that. (Their older 3DS commercials with the group of guys that made fun of that one other guy (descriptive, I know.) were pretty good too.)

#3 - Nintendo has never needed a Hardcore Character. They won't need one now. Plain and simple.

#5 - The GamePad looks fine and feels perfectly fine. All Nintendo really needs to do is to up the battery and they won't be hard at all.

The rest of your points are fine. Some are kind of pretty good ideas, actually.

If you are talking about the first point no I meant make small games worth $60 or whatever they cost as long as they are retail. If you are talking about the user account yeah something like that, 

More like Steam actually. According to developers the Wii U eshop has a lot of similarities to Steam, in terms of being able to offer deals for their games whenever they want. That actually happen during the holidays, most indie games had a discount. As far as I know the devs themselves can't make discounts on either Xbox Live or PSN, not sure about this though.

i think people forget that nintendo gave up on the gamers market, they admitted they were looking for a different market with wii and they found it. the only problem is IMO that market is not the kind market you can rely on, its not a market like the 360/ps3/apple where you upgrade the tech, and people will be all over it, its a market where you have to creat something totaly unique and captivating and that market is a hit or miss, mostly miss though.

I would love to see a link where Nintendo said that...

Nintendo only said they were expanding their market in both casual and cores (although they never said those exact words I believe). Nintendo knows they have lost some of the core gamers during the Wii and the Wii U is their answer to get them back, whether they will fulfill that or not is another discussion.  

I think what he failed to say is that Nintendo doesn't follow the gamers they create into adulthood. Those who stay behind, really do so of their own accord. Sony hasn't had a problem taking those gamers away and neither does Microsoft. They consider their consoles the step ladder from Nintendos.

Microsoft admits the Wii will set up their serious gamers to "graduate" to the Xbox:

"Yeah, absolutely. I think that there's a difference in the type of customer that is buying the Wii. When you think about it, there's a difference between trying to be the number one console with nine year old gamers, and being the console that offers the most experiences from 13 to 33. 

I think for us, we don't really see the Wii as a direct competitor, we actually very much complement the Wii experience. It's obviously clear that we're going head-to-head with the PS3 in this generation. I think what Xbox will be able to do as well as the Wii is grow the market. 

In this generation we're seeing record revenues for the U.S. and globally for the business, and we're seeing more people buying and playing games than ever before, and the Wii is definitely part of that. And as they grow that pie, that benefits us too, because those customers are eventually going to want to graduate to an Xbox 360 experience."

That is mostly based on opinions. A lot of adults play a lot of Nintendo franchises till this day. I see it that all over the internet. If you feel Nintendo franchises are for kids then that's your opinion and It doesn't reflect the gaming market. I don't see Sony or MS "taking" those gamers, most gamers will play on all consoles (and enjoy their games), they will obviously have preferences, but that doesn't mean they are taking them.

Edit: at your post above. That purely PR talk, Nintendo gamers didn't "graduate" and move to other platforms. The Wii sold a lot because it was targeted to casuals (nobody argues that), but a lot of those sells come from gamers who want to play Zelda, Mario, Metroid, etc. If the gamer had desires to play 3rd party games they would simple buy a 360, PS3 or a PC, but some gamers didn't "move on" from Nintendo. 

Super Mario is not intended to be a "hardcore" character. I've studied color theory and Mario was created to attract children on a mainstream level after the arcade days. His cartoon style is created not for adults but to attract children (just like he attracted me and I am sure you as well), and primary colors are also in his outfit which are very attractive pigments to children. Nintendo knew what they were doing when they had Miyamoto create him. Sure you can be a hardcore fan of Mario, but Mario is not a hardcore character he's a light hearted, fat plumber who saves a princess who wont give him any (shhhh dont tell the kids that).
