Its possible, but unlikely. It might even up the console race in the short term though.
Right now Wii is roughly 500,000 Consoles Ahead. Halo 3 Launches in roughly two weeks. If sales continue Wii will have around a 750,000 Unit lead when Halo 3 hits. Best case the 360 movies 300,000 units in a week for 3 weeks, and it'd still be behind.
Unless the 360 has an insane holidayesque type couple weeks of like 400,000 Units a week, its unlikely.
