I had already posted this issue on my blog beforehand. Now that Windows 7 has been released, there is a growing demand to have a 64bit Flash player. (Actually, as I have scanned the web and in the Adobe bug database, it was requested since 2001 for 64bit Windows XP.) I suspect that there has been a big push for Flash player development across the mobile community and feature development for Flash 10.1.
The only suggestion that I can make is for our developer and user community who love flash to demand for a 64 bit Flash player on the bug database. (http://bugs.adobe.com) So sign up, and make your voices heard! Adobe does listen, its looks like a matter of priority and demand.
