I don't see MGS4 outselling Halo 3. Not any time soon.
Halo series tends to really stay alive as far as sells throughout the year. Halo 3 will always be in the top 20, top 50. And generate some really good sales. MGS4 just sees to only cater to the fans more. I really don't see regular gamers who never played MGS series before jump into the mix.
If Sony markets the game well...then we will see MGS series make a turn around. But I don't see this game competing against Halo 3 as far as sales and hype.
