the 3DS is beastly

I expect it to go as high as 16 if not 32 GB by the end of it's life like the DS went from 8-64MB at launch to up to 512MB (A.S.H. the biggest game I know of was only 256MB tho)

I'm not sure, but I think Ninokuni comes on a 512MB DS card.  Its the only game currently to do so

Btw, the linked text is in Chinese, not Japanese.

And 8GB ought to be enough for anybody! ... for now.

It may go higher.

DS ended up having half a Gb cards.

It may go up to32Gb, but now whats all that storage for is the question.

Copy protection, mandatory system updates...

is it confirmed? I heard rumours  that it would and that nintendo's supplier was going to be making a large batch of 512MB cards but I wasn't sure that it was that big.

'A 4gb card works out to 512MB, around the size of your average Playstation game'

Also allows for less need for texture and audio compression, higher resolution textures, high end voice overs and more.

Let's hope for the best. Many games on the DS had very grainy and bad textures. The additional space should help a lot.
