In addition, Team Ninja confirms that the game lacks Samus's Gravity Suit.
In a segment of Iwata Asks, members of Team Ninja stated that Metroid: Other M will come on a dual-layer DVD disc in order to hold the game's cutscenes and additional content. At times the cutscenes were shaved off in length by seconds to fit them all on the disc.
The development team also confirmed that Samus's Gravity Suit will not be in the final version of the game, instead replaced by a purple aura. A major suit upgrade seen in previous Metroid titles, Team Ninja expressed that series creator Yoshio Sakamoto felt that the suit's coloring made it look weird during certain serious scenes near the end of the game. He requested for the team to include a different indication that the player has obtained the gravity-related upgrade.
