Well, Nintendo said that they wanted to improve their relationship with small devs and there were articles saying that the conditions that Nintendo offered them were very good, so yes, it's possible that they convinced them to port their games on WiiU.

It's either that or the lack of third party games that make every indie game shine and be more visible than they usually are

I`ll go with answer number one and two! :D
Yeah, i think it`s a little bit of both.

Another eShop game for Wii U!

It`s called Anothe Castle and will be released next year.
You can check some images of the game aswell as a small video here: http://www.nintendolife.com/news/2013/02/retro_platformer_another_castle_is_coming_to_the_wii_u_eshop

^Interesting rumor. Eurogamer also has pics of the curriculums that show it

^New ways to show off what the Gamepad can do! XD

^ The shooting arrows and the music video were pretty cool!

Proud new owner of a Wii U (ZombiU bundle)! Loving the console so far and Nintendo Land's single player is better than I thought it would be. I'll sometimes play around with it with my family.

I'm trading in ZombiU because I don't like horror games (or horror in general). The least I can do is try it out. I mostly bought the bundle so I can get the Pro controller on a discount.

Nintendo Land is a really good game!
Too bad that if you don`t have anypne to play it with, you can`t play 3 main games.

Holy crap, you get credit from the free Nintendo Land download from the ZombiU bundle! That means I got 599 points for the Deluxe Digital Promotion for free!
