Well look what we have here. Somehow we've managed to come across pictures of a few Ice Cream Sandwich widgets. Specifically Gmail, Email, and Calendar. And to answer your next question, no, sadly, we can't hook you up with a download. We'd love to, but the widgets would actually need ICS to work.
It looks like they are all getting a nice coat of polish - we've helpfully included the old Honeycomb widgets for comparison (there are no equivalents of these in Gingerbread as far as I know, outside of an old and ugly simple calendar widget).
