uhh...it will have Nintendo Network capabilities. That's how it will work through Wi-Fi. And in the GC original you could catch Wisp, the ghost, who could make your town completely free of weeds. I'm sure Mii's will also be an option, since they were in AC:CF. (Although IMO they look kinda ugly and don't really fit Animal Crossing)
Just today I was thinking about this game again...I really hope it comes out right at the end of school. I wanna play it all summer, but if I get it now my grades would suffer.

Soon the 3DS should have an update that lets you buy packaged software, like PSN, right? I'd like to buy this as a game card, but I'd
LOVE to buy it as a downloaded software on my 3DS. Even if I had to upgrade my SD card to fit it. (Although the original N64/GC one was ~20 MB, AC:WW was ~64MB, and AC:CF ~300MB. So I don't think it'd take up too much space, surprisingly.) I just think it'd be nice to be able to play this game without going to have to search for the game card. Or maybe it's that I'll want to have the ability to play my other 3DS games, cause if this wasn't downloadable I'd never take it out of the slot.
So yeah, I'm excited. A lot. This has potential, and I don't think Nintendo will screw it up.
Who actually reads these things?
