However, the company has been extremely short on details. During a speech at the Worldwide Partner Conference here Tuesday, Microsoft CEO Steve Ballmer didn't quite answer all the questions. But he did promise more news will come sooner rather than later, while also offering a few hints as to where the company is headed. During the presentation, Microsoft also pledged to share more information with partners and developers.

"This is an ambitious project for us but it is very important," Ballmer said. "We have a lot of news and things that we'll be talking about and unveiling...this year."

Ballmer said that later this year Microsoft will deliver the first version of a set of developer tools to build on top of Microsoft's Windows Live effort and noted that the tools will be based on .Net.

"We are in the process today of building out a services platform in the cloud," Ballmer said.

Doing so, however, will take time. It requires Microsoft to have a new computational model, a new storage model, a new virtualization model and more, Ballmer said.

Later during the talk, Windows Live general manager Brian Hall came out to demonstrate some of the existing partner opportunities. Hall also promised far more to come.

"Fundamentally, we are opening it up," he said. "What's ours is yours."
