As a follow up to Mark's post, some leaked data has revealed that the Xbox 360 will soon gain a series of customizable avatars which will take the place of your gamer pic. The Mii-like avatars are said to be fully customizable and are due out this holiday season. The information was obtained through the marketing research firm Intellisponse.

Below are some descriptions directly from Intellisponse:

"Avatars" are digital personals available this holiday for all Xbox LIVE connected members and this spring for all new console owners. "Avatars" will be used in place of the gamer picture you have today and give you a much more lifelike, animated and fully customizable persona for you to reflect who you are online.

With hundreds of clothing options to choose from your "Avatar" can truly reflect you each and every day!

Spend a few minutes or a few hours building and outfitting your "Avatar" to reflect the real you. The choice is yours.

Your "Avatar" will represent you as you jump into various arcade and retail games. You'll be playing in the games!
