I think WiiWare's improved greatly over last year if the games in the Euro schedule are on time and also hit the US this year. Last year was LostWinds, Sam & Max, Strong Bad, World of Goo and... LIT? This year there's Monkey Island, Swords & Soldiers, Bit.Trip, NyxQuest (which is better than anything that came out on the service in 2008), and possibly LostWinds 2, And Yet it Moves, the Magic Marker game that isn't the DS game, and Super Meat Boy among others I might have forgotten.
I don't see 2010 being much better than 2009 as far as the Wii goes, unless there are a ton of unannounced games waiting in the wings.
