On the heels of Microsoft's Internet Explorer 9 beta, which is available in a 64-bit flavor for Windows 7, Adobe has released a 64-bit Flash plug-in. Dubbed Flash Player Square, this preview plug-in is available for Windows, Mac OS X, and Linux, although judging by the "features" section of the download page, Adobe is clearly targeting IE9.
