Web search and content provider Yahoo! has announced that it will hold a major press event this coming Monday that will apparently offer news of its push on “rich online and mobile experiences, bringing forward a new era in keeping consumers connected.”

With no further details offered by Yahoo!, one has to turn to the ongoing mobile rumor mill to come up with a potential answer. The latest gossip revolves around “Project Nike,” an apparent partnership between the web services giant and mobile handset manufacturer Nokia; the joint venture would apparently see Nokia provide Yahoo! applications and services on its phones as a staple.

Until the press conference and corresponding announcement on the morning of May 24, 2010, we can only continue to guess but do check back for news when the company does reveal its plans.
