Much like he did for the just-launched New Super Mario Bros. Wii, Shigeru Miyamoto has announced that Super Mario Galaxy 2 will be "really difficult." But will it be so difficult as to require Nintendo's new in-game life preserver, the Super Guide? Miyamoto isn't so sure yet. "In general," Miyamoto told Official Nintendo Magazine, "wherever and whenever appropriate, I think we will want to incorporate that kind of thing, but I cannot commit to anything specific right now."

Here's our absolutely ridiculous prediction: Miyamoto and crew are going to do with this sequel what they did with Super Mario Bros.: The Lost Levels. Since Galaxy 2 is basically another level pack for an existing game, the team is going to make it almost impossible to complete.

Of course, that won't happen. More likely, Super Mario Galaxy 2 will be on par with the first game in terms of challenge, but will include the Super Guide to stay consistent with Nintendo's current strategy.
