Update: Google Apps Premier Edition launched this evening. See our updated coverage here.
We have a well placed but single source rumor that Google may make a major announcement tomorrow, possibly a statement of its “official” strategy around their small business focused products. If this is the case, it would likely involve bundling Docs & Spreadsheets with Google Apps for Your Domain into a single hosted offering. An announcment of an online PowerPoint application and/or other new products and features could be involved as well.
Earlier today the product manager for Google Docs & Spreadsheets, Jonathan Rochelle, spoke at the Future of Web Apps conference in London. He made absolutely no mention of any possible announcement.
