^^ Perhaps someone needs to take a chill pill

First off, Rare is not a publisher, they're a developer. Secondly, if you'd bothered to play past 5 minutes, or even open your eyes while it was on, you would have noticed that it does indeed support the touch screen - boost starts and golden balloon challenge for example.
Also, you do know that it is a port of the original N64 version, don't you? You speak as though it's a ripoff of Mario Kart DS, when it was based on MK64. IMO, it's a much deeper game than MK, and while the merits of the weapons and characters in each can be argued, DKR offers a much better single player/online mode than MKDS. DKR was hailed as one of the best Mario Kart-ish games and one of the best on the N64, and it was well suited to the DS.
Lastly, they ARE owned by MS. Nintendo has to give them permission to make a "kick ass new 2d/3d Donkey Kong game ala NSMB", they can't just decide to make one on their own.
By all means, eat your buffalo shit and get peed on, I hear some people are into that sort of thing
Meanwhile, I'll be playing DKR
