Is this Mario Kart 8's first DLC? Birdo, Diddy + real battle mode?

DLC for Mario Kart wold be so cool. I don't see why Nintendo never took the chance to make some extra cash by putting in some DlC for on of there most popular games on the Wii and now that Mario Kart 8 is quickly becoming the best selling Wii U game adding DLC just seems like a no brainier.

Also YESSSSSS if this is true Brido will be returning!!!!! Hope its legit.

I was actually hoping it would be free DLC. Partially because I'm an optimist, partially because I'd be outraged if I had to pay extra for Diddy and E Gadd instead of the babies.

I hear you, I dont really mind the baby characters but the kooplings take up way to much space. I would have rather just had Birdo and Diddy then the 7 kooplings. 

It would be ideal to get the DLC for free but that seems unlikely. But who knows maybe Nintendo has a plan to support Mario Kart for awhile with DLC releases and will give us the first DLC for free to get people into it.
