In addition to hearing about Office 365, Azure, Dynamics CRM Online and other cloud products, partners are likely interested in hearing about the Surface device, whose latest edition, the Surface Pro 3, is positioned by Microsoft as a tablet that can replace laptops.
Microsoft has been criticized for not making the Surface broadly available to its channel partners, opting instead to deal with a relatively small set of distributors and resellers.
Asked for comment, a company spokeswoman said via email that the company is "enthusiastic about the partner opportunity around Surface and we expect it to continue to grow with the introduction of Surface Pro 3."
In addition to the distributors and resellers it's involved with, Microsoft also has the developer-focused Apps for Surface program and the Designed for Surface program for accessory makers, she said.
WPC attendees will get to hear from Nadella live
WPC attendees will also get a chance to hear directly from Nadella, who is scheduled to speak on Wednesday, an opportunity for them to better understand his vision and plans for partners.
Under Nadella the company is more open to porting its software, like its Office crown jewel, to non-Windows platforms, like Apple's iOS and Android. He also will usher in significant changes in the coming months.
In a manifesto-type letter to employees last week, he stressed the need for Microsoft's culture to become more conducive to innovation and more responsive to customer needs and market opportunity.
He outlined changes for the engineering team, and retired the "devices and services" tagline his predecessor Steve Ballmer had used to signal the company's new focus, replacing it with his own: "productivity and platform."
Microsoft will "reinvent productivity" for individuals and businesses worldwide, he wrote, explaining that "productivity for us goes well beyond documents, spreadsheets and slides" and means helping people "who are swimming in a growing sea of devices, apps, data and social networks."
Some industry analysts and commentators, reading between the lines, believe that the letter strongly implies that a sharp reduction in the company's headcount is coming, although that is not explicitly stated in the text.
Content and Code's Wallis is looking forward to participating in a roundtable discussion with Nadella at WPC and getting to hear what he has to say about a range of subjects during his keynote.
He's been positively impressed by the new CEO so far, and sees similarities between Nadella and Bill Gates, especially their emphasis on the importance of innovation.
"I'm interested to see how Satya Nadella's changes impact Microsoft," he said.
