Pretty much spot on. What happened is Nintendo made it easier to develope on the Wii and it started getting that "PS2 bulk" as I like to call it. They get out the titles to sell off name and picture rather than actual quality. You can call it shovelware.
Thus what happened is the magnitude was there, and the main competition is for shelf space. Now, this has also brought some bigger titles to the Wii but they have not had the marketing or "publisher push" behind them to be able to "win" the shelf space wars that is occurring on Wii. Same thing happened on PS2 and you saw the big name titles winning... even beating out 1st party names. On Wii it has become the exact opposite. Nintendo, obviously, strongly markets there games and is easily winning the shelf space wars with a few developer's games picking up a victory every now and then.
So yes there push has allowed more quantity but that quality never came. And with the Wii now infringing on almost 1000 released games, marketing and advertising matter even more than they ever have... potentially more than PS360 games. Developers screw themselves by not having more money spent on their marketing and advertising... of course some spend so little on development so why should they.
