New Super Mario Bros.

So - to change the topic from manuals and koopa kids just a bit, its obvious to everyone involved (players, creators, etc) that New Super Mario Bros has been a ROUSING fantastic success.

So my question is - should the series continue as a franchise and bring back the "sidescrolling Mario's" that we lost shortly after Super Mario Land 2? Keeping in mind that the whole point and focus of the "New SMB" part of Mario seems to be "back to basics", what changes and additions would you like to see done based on how the first was handled. If so, what kind of things would you like to see done in a New Super Mario Bros. 2?

Personally - I would like to see them expand on things shown in 1. I'd like to see the return of the Poison Mushrooms. Lost levels was made significantly harder because of those things and they could really set off a good contrast to newer power-ups and bring down the "too-easy" complaint many have made with 1. I'd like more aspects of Mario 2 japan and maybe less aspects of Mario 2 USA. If they're going to take anything from Super Mario Bros 2 at all, it'd have to be the Shyguys. Shyguys are IMO the single greatest enemy addition to the series because they're just so absurd. Plus I can kind of already imagine them dancing to the music on screen.

No picking up of enemies or pulling vegetables, just keeping it simple, hop and bop kind of stuff. if they do include those aspects its needs to be simple and creative. Ideas from anyone else?

How ya doing, buddy?
