This has been up for a little while on the Embarcadero Delphi web page, but I am sure there are people who are interested in knowing more about the future of 64 bit delphi.
If you're willing to sign up for the Preview Beta, and you get accepted to the Beta, you can try the 64 bit Delphi compiler today! Check it out here on Embarcadero's website. According to the website, it's not guaranteed that all who apply will get in. A video is available at the website link where Embarcadero’s David Intersimone takes you for a tour of the Delphi 64-bit compiler.
