Bill "Texstar" Reynolds, founder and lead developer of PCLinuxOS, said in a blog post today that a new 64-bit version is in the works. Details are sketchy at present, but users have been asking for this for a long time.
Reynolds said that he has finished building the first 1000 packages. First he "upgraded gcc to 4.5.1, glibc 2.12.1, xorg 1.9.x then started rebuilding the libraries." Once those are complete he'll begin on the desktop packages.
