The Wii does have a lifespan beyond 2011 -- in Europe. Nintendo of Europe sent out a list (PDF) of upcoming titles today, including the two other games for which Operation Rainfall is campaigning: Mistwalker's The Last Story and Ganbarion's Pandora's Tower. Both are slated for 2012 in Europe now, and have yet to be announced in North America. The Legend of Zelda: Skyward Sword will be released in Europe November 18 while Kirby's Adventure Wii is coming in December.
The release list also provides November and December windows for Super Mario 3D Land and Mario Kart 7 on 3DS, respectively. Super Pokemon Rumble will also be released in Europe this December. On DS, DQ Monsters Joker 2 is coming October 7, Kirby Mass Attack is due October 28, and Professor Layton will answer The Spectre's Call in November. Cave Story will finally come to DSiWare in Europe in Q4.
A few standout downloads listed: in Q4, the 3DS Virtual Console will see releases of Super Mario Land 2: 6 Golden Coins, Metroid II, and the Game Boy Bionic Commando game. Nintendo previously blocked the NES version from Virtual Console.
