Yeah, that would seem to suggest it's available in an x64 version. But it really only states the OS requirements, not whether the app is native x64 or not.
I feel sure it would (should) be at this point in time. Just wanted a confirmation before I throw down that kinda coin for it... being as it doesn't give you a selection of 32 bit or 64 bit before you pay, and the demo download for Windows only says 32 bit.
