At FlashForward, Flash Player engineer Tinic Uro demoed a forthcoming version of the much requested 64 bit version of the Flash Player. No release dates, but we'd say this really confirms Adobe's commitment to be on all platforms.
Windows, OS X, Linux and other Unix flavors come in 64 bit versions. 64 bit software won't necessarily run faster than the 32 bit systems most of us use, in fact, they will sometimes run slower. 64 bit platforms offer a great advantage though - they can address more than 4 Gigabytes of memory and for some applications this is important. There is not a lot of 64 bit users around, it's in fact so few that it's hard to find good statistics for it. There have however been a lot of requests for this at the Flash Player Team's various blogs as running the 32 bit player in a 64 bit setup can be a bit of a hassle.
Now there is an answer. Via Brooks Andrus, we found this post by Alexander James Bustin where he tells that Flash Player engineer Tinic Uro demoed the 64 bit Flash Player at the recent FlashForward conference in San Francisco. Not only that, he also showed parts of the source code and did some "live bugfixing" while presenting (that's pretty hardcore...). Shortly after, Mike Melanson (also a Flash Player engineer) posted this "random note" that seem to confirm what Alexander saw. Obviously, this is still early days and no date has been confirmed, but stay tuned to kaourantin.net and penguin.swf for official
