SSBBrawler: Actually, I’ve done the math, and I have come to a conclusion that may or may not put this whole storage concern to rest. A quick disclaimer: I have no formal knowledge of electronic storage, and I was using my 3DS for my calculations. Give me a break, it’s all I have at the moment.

Right now, my 3DS has an SD card worth 2 gigs of memory. On that card is 7 games, each using varying amounts of storage space (the lowest being Sonic Triple Trouble with 52 blocks, the highest NSMB2 with more than 2,700). With more than 6,000 blocks of memory left, I figure that I can download a minimum of 4 more games (assuming all use around 1,500 blocks) before my card finally runs on empty. This makes a total of 11 games for 2 gigs.
Applying this to the basic package Wii U, assuming it runs on the same principles I’ve been working with, through calculations that would take too long to explain here, I’ve deduced that it can run a minimum of 11 downloadable games worth 1,500 blocks each, with somewhere around 1,100 leftover. Now I can’t imagine the retail games will take up too much space on the console, not more than 10 or 15 blocks worth of save files. By my calculations, that amounts to about 73 retail games minimum.

Now, as I said, I have no real idea if what I’m saying is even accurate, and even when the console is released, I still won’t have any real idea how the whole storage space thing will work. That said, if the real thing is anything like what I’ve described here, even 3 gigs should be plenty for the average gamer.
