In response to the rumor about the likely future price of 3DS , here is a second rumor that comes directly from the manufacturer Macromix. Indeed, it informs us that the cartridges for the future 3DS vary between 1GB and 8GB!
So the 3DS can store up to 8GB data cartridge, leaving a lot of free rein to developers! Hopefully still do not see too cartridges "full vacuum"! (Humor in reference to the Nintendo DS!)
