Scrivener only 32-bit

I’ve just seen in the activity monitor that Scrivener is one of the few apps on my computer that isn’t 64-bit and I just wondered if this limits the maximum size of any documents or if there are any other possible points to be considered as a result? Are there any plans to become 64-bit?

Just another thought I’ve had. How is Scrivener looking for compatibility with Mountain Lion? I’ve heard rumours that it is due out much earlier than originally expected, though I have yet to see anything of great interest so far to encourage an upgrade. Perhaps Apple has something secret hidden up their sleeve.
