Major Nelson has annnounced that attendees of this years E3 will be able to nab themselves an unique "prop" by visiting the Mcrosoft booth. People who do, will get signed up for an E3 trophy that will be available to them later this year when the props officially launch. here's the word from the man himself:

"One of the new features we have is called props which will allow you to add cool new items for your avatar to interact with. If you are attending E3 this year, you have a very special opportunity to get the very first prop: An 2009 E3 Trophy cup that will commemorate your attendance to this years show. All you need to do is drop by the Xbox 360 booth and sign up.

Later this year, we'll email you a code for your prop that you can download from the upcoming Avatar Marketplace. Look for the special sign up computer we've set up in the Xbox LIVE section of the booth. (South Hall, Booth 1523) If you’re having trouble finding the right section, it’s on the side facing Ubisoft’s booth."
