Sky Render on 15 March 2008
On a long enough timeline, both will outdo Halo 3, simply by virtue of the difference in size of user base between Wii and 360. It's very likely that Brawl will outdo Halo 3 first, however; it's easily the most anticipated Nintendo title in recent memory, and its predecessor sold to around 30% of the GameCube userbase in its lifetime. Brawl has been significantly more hyped and better designed, meaning it will draw a larger crowd. Though it's anecdotal and thus useless, I can say that it's drawn one person who previously had no interest in fighting games into the fray: myself.
Sky Render - Sanity is for the weak.
