It looks like Miyamoto and the programming team working on Mario 128,
the next major Super Mario Bros game, are experimenting with their
ideas, testing it out on Gamecube as well as the still in-development
next generation Nintendo console.  but it sounds to me like they'll
*probably* hold the new Mario game over for the next console.

GameSpy: What is going on with Mario 128?
Miyamoto: It's moving along secretly like a submarine under the water.
When developing, we often look at the different hardware and run
different experiments on it and try out different ideas. There have
been a number of different experiment ideas that we have been running
on the GameCube. There are some that we have run on DS, and there are
other ideas, too.

At this point I just don't know if we will see that game on one system
or another. It is still hard for me to make that decision. I am the
only director on that game right now. I have the programmers making
different experiments, and when I see the results, we will make the
final decision.

start from the beginning of this 4 page interview:

is that the impression you get from reading the above, that Nintendo
will hold the next Mario over to the next console, or do you feel
it'll still be made for Gamecube?
