E-world plus Eshop equals endless possibles.

Anybody remember the E-world and e-reader cards that came with Super Mario Advance 4 on the Game Boy Advance? I do. And I still wish that all the e-reader cards for E-world came to America. Of course, with the Eshop for the Nintendo 3DS, Nintendo could let you download Super Mario Advance 4, with all the extras E-world offers. I know I would get it if it came out. wouldn't you?
