Xbox 360 Roundup - 512MB Memory Card, Marketplace Updates, and more

Wait, don't buy that 64MB memory card for your Xbox 360! Microsoft has announced a 512MB card for $50 due on April 3. And, for a limited time, it will come preloaded with Geometry Wars: Retro Evolved. If you still want the smaller card, you'll be able to get it for $30 if you can wait a month. This move goes hand-in-hand with the news that Xbox Live Arcade games can grow as big as 150MB (up from 50MB). Upcoming Arcade games include:

• 3D Ultra Minigolf Adventures (from Sierra)
• Boom Boom Rocket (from EA's Pogo studio)
• Eets: Chowdown (from Klei)
• Jetpac Refuelled (from Rare)
• Pinball FX (from Zen)

If you're ready for a new Arcade game now, get online and download Worms ($10) And, for a limited time, you can get the high-def South Park episode "Good Times with Weapons" for free - if you have a hard drive and about 1GB free space. Since last week, Microsoft's pitch on South Park exclusivity has shifted from recent seasons (now available on iTunes) to high-def versions, though this freebie seems to be the only HD episode available right now. Speaking of free, if you skipped Crackdown but wouldn't mind winning a copy, all you need to do is register your gamertag on Warner Bros Web site and then watch 5 promo videos for the movie 300. Oh, and be lucky...
