I think my post is being picked apart only at it's weakest points. Why not address the fact that Nintendo is opening up the market to developers to make beginners games? The PS2 had plenty of shovelware, no one can deny it. But back in those days, I never heard a developer say their concentration on making their PS2 game was for a "casual" audience.
Monster Hunter for PS2 scored a 68 on metacritic. It may sell well, but it doesn't exactly scream quality. I'll give it up for Fatal Frame, because it's new developers are geniuses coming off of a near AAA quality game. Just how long into the Wii's lifecycle are we going to see the abundance of quality third party titles they should have based on it's market share? Year three? Year four?
Developers are not feeling the incentive to pull together huge teams to make Wii games. They see that they need them to be successful on 360 and PS3. They don't have endless amounts of spare cash and manpower. With Capcom still working on Resident Evil 5, Street Fighter IV and Bionic Commando for 2009, Rockstar finishing GTAIV, then working on L.A. Noire and the exclusive PS3 game for 2009, Konami trying to finish MGS4 and then bringing out Metal Gear Online, plus upkeeping it, Ubisoft finishing Rainbow Six Vegas 2, working on Splinter Cell Conviction for later 2008, and then Prince of Persia for 2009, plus the possiblity of the next installment of Assassin's Creed, Square-Enix working on the two FF XIII games, releasing new content for FF XI, finishing DQIX for DS, working on FFIV for DS, finishing the Last Remnant, Pandemic finishing Mercenaries 2 and then finishing Sabotuer, Bioware working on Sonic Chronicles for the DS, the new MMO, and KOTOR III(which could be for the Wii I know, but thus far have to figure Bioware will stick with 360 and/or PS3), Activision has shown that they'll let Treyarch put inferior Call of Duty's on the Wii but not Infinity Ward, etc. etc.
When can the Wii finally get a share of the pie?
The PS2, as someone, mentioned previously, already had an extensive third party lineup by the end of it's first year and 4 months, with plenty of great titles announced and on the way.

With a lineup like that, no one cared that the PS2 had shovelware. It wasn't affecting the developers from coming out with stellar titles. Honestly, even with Wii's success, do you see them having a year like that this year? Next year? Ever? Each developer is in a position that they develop a game for PS3 and 360 or the Wii. Once you take that into account, it doesn't matter if Wii is beating each console, because it needs to be a sweeter deal than developing for both of the other consoles combined.
