Improvements like?...

If it's Diddy Kong Racing I swear Nintendo will have gone back on all the progress they'd made since 2014's public apology. Not only is there no reason for two mascot kart games on the console (moreso considering Mario Kart is effectively Nintendo Kart now), putting all of those resources into a game that won't make any waves whatsoever would just absolutely disgust me. It's one thing when it's a Platinum side project, but if this were Retro's excuse to not make Prime 4 yet, I'd be VERY hard-pressed to continue supporting Nintendo.

Oh. I guess you will spto supporting Nintendo soon. All this gen has been the same story: software nobody asked for.

I love both Returns and Tropical Freeze...
I'm sure I would love another DK game...
Having said that, I can think of more than a few games I would rather get right now...

Fans asked for most of what was delivered before E3. Wonderful 101 was really the one exception, and maybe 3D World right before it was first announced. It's only this past month that they did some horrible curveballs like Amiibo Festival and Federation Force. If they throw a third at me, not even counting a couple other questionable moves they made at E3 that I'll put aside for now, I'll be furious. 

Watch. He's working on the next 3D Donkey Kong game.

THAT I'd be okay with. I'm one of the six people that legitimately enjoyed DK64 a lot. 

i'm fine if it is just a DLC for MK8. :D

I also would like to see that. I don't get why Nintendo stopped making 3D platformers that was my favorite genre.

Like vastly superior controls, better track design, more tracks, better kart selection, larger kart selection, better online, and a Partridge in a pear tree.
