"Wi-fi multiplayer battles over the Nintendo Wi-fi Connection are finally here, bringing voice chat with them. Also coming is the tentatively titled Map Center making map creation and sharing a worldwide affair. Players can take their map designs, upload them, and rate and download others via the Map Center adding hundreds of maps to the 170 already included."

Wow, and the map making community is rather strong with advance wars, this site http://www.advancewarsnet.com/designmaps/ has 6700 custom maps, even an entire campaign that is fan made.

So basically, the hundreds of already included maps that will come with it, + custom maps that are uploadable, online battle and voice chat = SATAN it will suck souls
