Miyamoto would like to do another Galaxy game, not before new hardware

This comes from an Eurogamer interview with Shigeru Miyamoto...

[A new Mario Galaxy] is always in discussion. But even with Mario 64 there was a lot of feedback about motion sickness with the 3D or maybe us making it too difficult.

Going back to our roots and making New Super Mario Bros., anyone can play that. So that's why we went back.

We're always thinking, is there a middle ground where people who do enjoy the 3D worlds of Galaxy and those who enjoy New Super Mario Bros. can both enjoy it? We're always looking at those opportunities.

...On the other hand, me and [Yoshiaki] Koizumi-san, director of Galaxy, are always looking to challenge Galaxy and do another 3D action title. However we can't make so many games at once in parallel.

But as the hardware technology gets better and advances, I think there will be a lot of opportunity for both options.
