I wonder if these games cost the same as regular games with only 2Gb(or smaller) carts.

That game by Mistwalker called Archaic Sealed Heat uses a two Gigabit DS card and it is considered the biggest DS game available. It is inevitable that DS cards are going to get bigger in size because the developers are finding new ways to cram as much stuff in there as possible. If the Playstation Final Fantasies were to ever come to the DS, they would be very big game cards that would be well over 1 Gigabyte a piece. Most of this is due to full motion video.

No they wouldn't.  Video compression technology has improved significantly since the PlayStation era.

The last time I've heard about the data size for games was during the Nintendo 64 years. Does this matter? Do people expect games which require more data to be better games?

It doesn't necessarily mean better games, but it doesn't hurt. There's a reason why each successive generation of game systems has increased the capacity of the game media.

I understand that, but it has been a while since companies talked about the size of individual games. I guess that's mostly because ever since switching to discs, the media has a set limit which can't in any way be exceeded. That doesn't mean every game is that size, though.

I guess this isn't really being announced as a selling point, more of a fun fact. Like how Super Smash Brothers Brawl being released on the first dual-layer Wii disc wasn't advertised as a feature.

It wasn't, there was another one, but few people played it.  I don't recall what game is was.

For the DS, it's really not all that important, either.  It's more like an announcement that things are progressing with the handheld, if anything.

Cartridges :P

thatguy is right, the only time that the size of DS games is mentioned is when they make a bigger size card for it (I remember when they reported the first game to use a 1 gigabit card, and the first to use a 2 gigabit card).

in the year 2025 you can buy a terabyte sd card for about 16 dollars :P

2025? I think you're 10 years too late on that...

you think you'll have 1000 gigabyte sd cards for under $20 by 2015? Its 2010 and i can buy an 8gb solid state drive for about $25
I'll Concede to 2020, on the other hand i bought a 1TB HD for $99 at the beginning of the year, but im talking about no moving parts.

It seems, on average, every year-ish the amount of memory you get doubles for the same price.

So, this year, you can get a 4GB Flash Drive/Memory Card for about $10.  You can find 16GB Flash memory for about $20.
2011 - 8GB -32GB
2012 - 16GB - 64GB
2013 - 32GB - 128GB
2014 - 64GB - 256GB
2015 - 128GB - 512GB
2016 - 256GB - 1024GB (1TB)
2017 - 512GB - 2TB
2018 - 1024GB (1TB) - 4TB

Four TB on a little flash drive.

My first computer had a 1GB hard drive.  And it was very high end at the time.

The standard for ultra-high capacity SD cards (SDXC) has already been approved at a cap of 2 TB and the first 64GB card is about to hit. Based on what UncleBob mentioned, 2015 or 2016 seems like a reasonable timeframe for release of a TB SD card.

As for when it'll hit $20... dunno. Probably 2018 or so.

and on the hard drive bit , Nintendo has never seemed too interested in hard drives, but because of their now low price things could change.
