I predict more DLC and user generated content in the future - and given both are fairly emergent right now, and the videogame industry (economic downturn excepted) is on a growth path overall, it's pretty obvious you're going to see more of most anything that has an audience and not less.
Also, somedays it will rain, and some it won't.
Also, I'm sure Miyamoto took notice of the fun element for many in LBP sharing and playing levels and saw how well it could fit the Nintendo staples such as Mario.
Try to be reasonable... its easier than you think...
