Mario & Luigi: Bowser's Inside Story

Mario & Luigi RPG 3 (tentative title) is the upcoming third title in the Mario & Luigi series. It was confirmed on October 2 at the Fall 2008 Nintendo Conference and is currently slated to be released in 2009 for the Nintendo DS.

Plot
It is currently thought that the story takes Mario and Luigi across the Mushroom Kingdom to solve the mystery of and find the cure for a deadly disease plaguing the land. This would explain the giant Toads in the hospital. At one point, Bowser also tries to kidnap Peach, but he fails. In a second attempt, he uses something called a "Lucky Mushroom?" which gives him the ability to inhale everything. He uses this ability to eat Peach, along with Mario, Toadbert, and a yellow Bob-omb.

It is also speculated that Fawful may be an antagonist in this game, since some enemies bear a resemblance to him. The Flying Saucers featured have green domes instead of the purple of Shroob Saucers, and are speculated to belong to Fawful.

Gameplay
The trailer shown at the conference was very short, but one could see a giant spherical Toad rolling on the screen, Mario and Luigi using a Green Shell on a green bug-like enemy, and Bowser using Fire Breath on two tree-like enemies.

Battles seem to have changed little, with Bros. Items making a return. Bowser also has a system of attack items. A new element has been added to battles, a meter at the bottom of the screen with Mario and Luigi's heads on it. It is currently unknown what purpose this meter serves. Additionally, there are now six categories of attack during battle, as opposed to Mario & Luigi: Partners in Time ' s five, or Mario & Luigi: Superstar Saga ' s four. No details about the sixth type of attack are known.
