For those who are into such things just a few hours ago full details have been given over Sims 3 coming out on PC in 2009. Below are the full PR bits covering all the new features. What is also interesting is how the game will feature a new game engine.

========
New Seamless, Open Neighborhood the Neighborhood Freely.

See the sights with your Sims! The new seamless neighborhood architecture allows your Sims to roam freely around the neighborhood and visit their loved one and friends—or foes. Discovering other Sims homes and families, traveling around to new locations like City Hall or the local park will create a whole new way of life for your Sims. Storytelling options will multiply as your Sims stroll downtown to meet new acquaintances, head across town for lunch, spy on their neighbors and bump into the boss when they least expect it.

New Create A Sim—Create Any Sim You Can Imagine.

In addition to the open, living neighborhood, the all-new Create-a-Sim interface will feature easy-to-use design tools that allow you to make truly detailed Sims that are more realistic than ever. Create-a-Sim gives you the incredible freedom to customize just about any Sim you can imagine. From thin to full-figured to muscular—everything in between and even the extreme! In addition to determining your Sims body shape and size, you will also be able to fine-tune every feature on their faces, customize their hair style and select their skin tone, all from a vast selection of options. With so many choices to choose from, it is fun to create more realistic characters that look like you, someone you want to look like, or even a famous personality.

New Realistic Personalities—Every Sim Is A Unique Person, With A Distinct Personality

With the innovative and proprietary Realistic Personality System in The Sims 3, you can attribute each character with five distinct personality traits, helping shape your Sims behaviour and how they interact with others and their surroundings. This new system will empower you to create extremely complex and diverse in-game personalities. Will you create the nosy, inappropriate, kleptomaniac grandmother who loves to meddle in other people’s business? Or the commitment-phobic, hot-headed punk rocker whose rude nature and childish disposition keeps him from scoring a date? In The Sims 3, Sims will go beyond the basic set of day-to-day needs to be distinct individuals with multifaceted personalities, who can focus both on short-term opportunities and long-term goals. With a wide selection of personality traits to mix and match, more than 700 million combinations of Sims await. You never know who’ll meet in The Sims 3!

New Unlimited Customization—Everyone Can Customize Everything!

New and accessible creativity tools in The Sims 3 make it simple for anyone to customize anything, anywhere! From floors to flowers, fashions to sofas, wallpaper to window shades and more, The Sims 3 gives you all the flexibility and options you need to be the architect of your dream house or explore your interior design skills to outfit your ultimate home. Your Sims can make home an ultra-deluxe mansion, a cool bachelor pad, family’s dream home or charming cottage. The choice is yours in The Sims 3.
