Since it was revealed that Kid Icarus: Uprising will feature a 3 vs 3 Deathmatch and 6 player free-for-all mode, it's been unclear whether it would feature online play. Shedding some light on that question is Masahiro Sakurai, who recently answered user-submitted questions on IGN. One of the questions prompted Sakurai to reveal his intentions regarding online play.
When asked: "Will the multiplayer mode be online as well as local?" The response wasn't a solid answer, but Sakurai said:
We're still in the middle of looking at the options for the wireless multiplayer mode, and I would say it's not totally out of the realm of possibility that we might end up not being able to implement the Wi-Fi online mode, but we're moving forward in development with the understanding and intention of making that a feature".
Kid Icarus from the NES could also be getting a 3D re-release on the Virtual Console. Sakurai hinted that it's a possibility and he had recently been in some talks about it.
