No, you're wrong. Eight years ago was January 2012. Here's a list of the best games (by no means all, and not including WiiWare) released for Wii after that date: Xenoblade Chronicles, Rhythm Heaven Fever, The Last Story, Project Zero 2, Vampire Crystals, WWE '13, Mario Party 9, Disney Epic Mickey 2, Transformers Prime, PokePark 2, Pandora's Tower, Kirby's Dream Collection, Rodea the Sky Soldier, Skylanders: SuperChargers, FIFA 14 & 15, Lego The Lord of the Rings, Zumba Fitness: World Party, Zumba Fitness: Core, Pro Evolution Soccer 2013, The Hip Hop Dance Experience, NASCAR The Game: Inside Line, NBA 2K13, Madden 13, Harley Pasternak's Hollywood Workout, Lego Batman 2: DC Super Heroes, Pikman 2 (NPC), Major League Baseball 2K12, and no less than 12 Just Dance games.
And Just Dance 2020 for the Wii, by the way, has over 800 (!!!) reviews for it over on Amazon.com, proving beyond a shadow of a doubt that those of us who bought it for such games are still willing to purchase new ones. As we have every single year since 2009.
As for Wackipedia, never ever expect a page on that site to be accurate or up to date. And never claim that someone is wrong because they don't agree with something on Wackipedia. Their lists of Wii Motion Plus and Balance Board games are missing several that I am aware of. It has some nice articles. But it is neither official nor authoritative, and it never will be.
As to the original question, a list of Wii exclusives is perhaps the most useless such list for any console imaginable. The experience of a Wii game that was also for the X360 and PS3 (Ghostbusters, for example) is going to be so different that it might as well be an exclusive. (Ghostbusters on Wii is a million times better than on the HD consoles, just as Resident Evil 4 was and for the same reason: The Wiimote.)
