From IGN: "Way back when the Nintendo DS was revealed, Nintendo veep Reggie File-Aimes mentioned that cart sizes could go up to a gigabit in size. Or, more specifically, 128 megabytes. Several high-profile games have hit that point in just two years of the system's life, and more ambitious developers will demand more space for their products. With full-motion video sluts like Square Enix fully on-board the Nintendo DS train, Nintendo will likely put two and four gigabit cartridge media (256 and 512 megabyte) on the development order sheet in 2007 to encourage PlayStation-like game presentations with enormous rendered cutscenes, introductions, and endings, as well as voice-overs and full-on licensed soundtracks. These carts would, of course, be made at a premium, with the prices passed down to the consumer in higher game costs."

I can't wait to see the new games that come in more memory. With more memory, means better graphics. But better graphics don't always mean better gameplay. I'm just hoping that there will be a super smash brothers for the DS that would go with either the 256MB or 512MB. Discuss?
