TG2 will be fully multithreaded for the final release. That means the renderer, including Global Illumination, will support the use of multiple CPU's and or CPU cores in a single system, which will of course greatly increase render speed.
TG2 definitely runs on 64 bit versions of Windows. I have run it myself on both XP x64 and Vista x64. This is not particularly surprising though since the vast majority of 32 bit applications run without problems on both OS's as they include a 32 bit realtime emulation system for 32 bit. Note that a properly 64 bit optimized version of TG2 will be made available at a later time and this will help in particular with very memory-intensive scenes for those who have lots of memory (4+GB).
You can purchase the animation "module" separately as an upgrade for TG2 Deep. The animation module will not be finalized at the same time as Terragen 2, but basic animation functions are still available and are enabled by the purchase of the animation upgrade. Improved animation capability
