Reasonable on 04 August 2010
Pretty leading "What if".
Given Halo is widely acknowledged with driving Xbox sales and giving MS the lead in online FPS on consoles it's fairly likely that, unless MS where very lucky, without Halo they'd probably have failed to make enough gains in the videogame market.
I suspect FPS/Online would have come to consoles anyway, but without Halo it would have taken a lot longer.
You've gotta give MS credit for buying up Halo / Bungie as just what they needed for the Xbox. The game literally made the console.
Try to be reasonable... its easier than you think...
