The latest rumors report that Nintendo has three aims with the enhanced 3DS Lite:
1) Quicker menu screens
2) Improved Battery Life
3) Slimmer model
But if the rumors are true, aren't they missing the most important function: A Second Circle Pad. No one wants to be lugging around a clunky Circle Pad Pro wherever they go, so it's imperative that Nintendo include it as part of any new 3DS model.
