Xbox Live Marketplace - Free Halo 3 map and Sudoku puzzles, and not much else (though probably a price cut!)

For the second week running, the biggest news is the unrelenting rumor of a $300 Xbox 360 due to hit stores this Sunday. If true, you'll know before I do - I'll be off on my 17th wedding anniversary with GrrlGotGame. Here's what little you can download from Xbox Live Marketplace while you wait and see (assuming you already have a 360!):

• Halo 3 Cold Storage map (free)
• Rock Band tracks ($2 each) "Closer to the Heart" and "Working Man" (this time, not a cover!) by Rush and "Snow (Hey Oh)" and "Tell Me Baby" by Red Hot Chili Peppers
• Arcade: Golf: Tee It Up! ($10) and Schizoid ($10), plus Buko Sudoku Puzzle Pack 2 (free)
• Game Videos: Civilization Revolution, Command and Conquer 3: Kane's Wrath, Supreme Commander, Too Human and Unreal Tournament 3
• Themes: Buko Sudoku, FaceBreaker, Golf: Tee It Up!, Prizefighter and Schizoid ($1.88 each), plus NCAA Football 09 ($1.25 each)
• Pictures: Buko Sudoku ($1.25), Command and Conquer 3: Kane's Wrath ($1.25), Golf: Tee It Up! ($1), Schizoid ($1), T-Mobile (free; enters you in a sweepstakes), University of Florida ($1.25) and University of Virginia ($1.25)

No demos this week, unless you count the free samples of the Arcade games...
