Search Engine Land reports that Google sent out invites for a sneak peek of a next-gen Google search. The press-only event is to be held tomorrow, September 8, at San Francisco’s Museum of Modern Art. The colorful rainbow-themed background featured on the invitation sheds little light on a possible agenda.

The “Search on” headline, however, most likely means that the Mountain View, California-based firm will announce new search products and/or update the existing search portfolio with new features. The accompanied text teases with the hints of something big going on with Google search between 9:30am and 1pm Pacific. It reads as follows:

We invite you to join us on Wednesday, September 8, to share our latest technological innovation and to get an inside look at the evolution of Google search.

The presser will be headlined by Marissa Mayer, Google’s Vice President of Search Products and User Experience. Other speakers include director of product management Johanna Wright, distinguished engineer Ben Gomes, and senior staff software engineer Othar Hansson.

Needles to say, the blogosphere went abuzz with rampant speculations relating to Google’s announcement. Some folks are convinced that we’ll see Google unveil a cloud-based iTunes killer tomorrow, while others point out that the choice of a venue is a nod at an improved Google Goggles version. We’re wondering what’s your take so please cast your vote below.
