Wow, this is tremendous news, imo. Why? HRC is something that I DID NOT expect them to incorporate online. What does that mean? It virtually confirms that everything I DID expect to be online will be. This proves that Nintendo is going all-out with this games online capabilities and that is great to hear.
HRC in general looks great, with all the new modes. They might actually get me to play the mini games fairly consistently (HRC, BtT, BtP, etc.).
*Wonders where the stadium will go in the menu now that it can't go under "1P Mode"*
