Hear me out on this, fellow Martians VGChartians, I believe Retro's game is going to be a launch window title for Nintendo's Next console for some good reasons and here are they:

1- Retro's last game was Donkey Kong Country: Tropical Freeze, which was released back in February 2014. 

2- Despite that, they allegedly started developing their next game back in November 2013; so even if their new console releases late this year, the game would have a good 3 years of development, akin to their previous games.

3- The game may have started its development for Wii U, but certainly won't be released for it since Nintendo is not announcing anything major for it since a very long time.

4- Nintendo needs a good initial line-up of games to convince people, and preferably one that doesn't rely only on a Zelda port + some Mario game, that's too obvious.

Your thoughts?

I believe you're right!

Makes sense to me

If not launch, first year for sure

Completely agree.  The last thing Nintendo wants is another 9 month long game drought after launch that will kill their console.

I've always thought so too. It might be Prime, but if it's not, it better be some original IP.

I really hope so, it would line up perfectly.

Is there any rumor on what might be Retro´s title?

I'm not sure if it'll be a launch title, but I expect it'll be out within the first 12 months NX is on the market.

I don't think so, but it will come within the first year of the NX

Tamaki from Unseen64 confirmed that the game they are working on was picked by Retro and not by Nintendo as for what happened with DKC: TF

I think it's certainly possible, or, if not on the launch , in the first 2/3 months following it for shure...
