Nintendo has refused to be drawn on whether mini game collection Nintendo Land will be a Wii U launch title.
Project lead Katsuya Eguchi said he "honestly didn't know" when questioned at an E3 roundtable today.
However, he told the audience that the game will have the same relationship with the Wii U that Wii Sports did with Wii, and suggested we draw our conclusions from that.
He added that while Wii Sports was bundled with the Wii in Europe and the US, it was sold separately in Japan, so the package may differ depending on territory.
Eguchi also showed off a little more of the game following its reveal earlier in the day, showing a brief glimpse of an F-Zero-themed racing event.
