1. HD remake.... last nintendo direct gave us Mario Galaxy 2 on WiiU .... this is pretty bad business by nintendo. They could of made a HD remake of Galaxy 1 & 2 and bundle them for $50. This can be handle by outside studio and boost software available to WiiU. There so many games that could benefit from the HD treatment.
2. WiiU consoles colour scheme... Black and white??? Nintendo has gone down this path before and it has result in short term increase in hardware sales. More limited edition WiiU's that would boost sales and put the focus on Nintendo WiiU if only to generate some news.
3. WiiU Slim or WiiU redesign... rather then change colour release a new redesign WiiU. WiiU 250-500gb anyone?
4. Every new game should have get a limited run WiiU bundle, software sales consoles and what better way to boost sales then to try to entice new customer with a limited edition bundle.
5. Price cut.... MSRP has been $299 since August 2013, sure price cut is not the only solutions but it's certainly not going to hurt. The only way to boost softwares sales is by increasing the current install based. Lost revenue on hardware is quickly made up in periphiral and softwares.
6. More software, sure Nintendo by now has completely lost third party support, It's time for Nintendo to build a staple of 2nd Party partnership studios. Nintendo cant make enough software to prevent software drought and there enough struggling studios in Japan and around the world that could use some security that nintendo can provide by funding their game development.
7. Better use of Nintendo Direct, I think there should be a monthly Nintendo direct that focus on every WiiU and 3DS games coming out in the near future. These Nintendo direct should no longer feature Iwata and his broken english (I'm not saying drop Iwata entirely just doesn't have to have him do every Nintendo Direct) , Nintendo has large marketing such as the Tree House and Bill Trinen that would be much better a conveying the Monthly Nintendo Direct message. Let marketing do their job.
8. Capcom.... buy them enough said.
9. Bring more Apps to the Nintendo WiiU, allowing for more diversity will have people using their WiiU more often. Give people reason to use their WiiU every day will increase interest in the WiiU and may generate positive word of mouth advertising.
10. Recapture the casual market, Xbox one and PS4 aren't really focusing on this market segment either.
