Release Date for IE 7 (and the min/max-width property)

Has any one heard a (recent) projected release date for IE 7?

I'm working on some pretty major revisions to my work website that involve max-width. At high resolutions in IE 6 the site looks pretty stretched out. I'm wondering if I should go ahead and release the updates anyway or if I should wait until 7 comes up and supports that property. It's not a major rendering problem, it just looks a little distorted and I'd prefer that users see it with the max-width.
