3rd-party sales are still bigger on 360/PS3 combined! so there :p
The graph is through May 2008 for Wii/PS3 and May 2007 for 360, by the way, and shows NPD (US) figures.
What's interesting is the slope. Wii has sold 10 million 3rd-party games in the first 5 months of the year in the US alone, with not many big sellers but a lot of little ones (including Okami, Boom Blox, and others). This despite Smash, Mario Kart, and Wii Fit all releasing in that time frame -- third-parties stared in the face of Nintendo's biggest games of the year and still sold a cool 10 million.
As compared to 6 million for PS3 -- without MGS4 but with GTA4, DMC4, R6Vegas2, and Haze.
360 had 7.5 million in the first 5 months of 2007, which had I believe stuff like Guitar Hero 2, Rainbow 6 Vegas, GRAW 2, C&C 3, Lost Planet, not exactly slouches.
Not to mention that a typical Wii game is less than a third the cost of a typical HD game, with most of the Wii games released much less than that even.
