Iwata's Keynote Speech

[vonboy]

let's see. this isn't exact, but a 2gb card has about 18,000 blocks on it, so you could store about...

-60 300 block games(the larger games, like world of goo, paper mario, sin and punishment, ect.)
or
-90 200 block games(some n64 games
or
-180 100 block games(some n64 games)
or
360 50 block game(snes games)

nes games are even smaller than 50 blocks, but you can only have 240 files on the sd card (well, ir'll only detect 240 different channels on a card), so not all those 50 bloack games would fit anyway.

if you EVER get 240 channels on a card, you can just use the rest of the space for game dlc, savegame backup, pictures, ect)

EDIT: i did some more fuzzy math, and i think even if you bought 240 of the largest possible size games, (i think it's 320 blocks, but i'm not certain) you could conferably fit them on a 16gb card or the majority of them on a 8gb card (all those games would take up about 8.5 gigs of space, so it would just barely be too much for an 8gig).
