Yes and new programs are 64bit, but as I stated, but it doesn't make sense for a publisher to go back to their entire catalog of applications and spend money on making them 64bit - especially if they support other platforms.
Take 1Password, they started out as Mac only but have made recent decisions on the latest version to streamline its development to the chagrin and anger of the mac community. Yet at this point, the Mac platform represents a smaller percentage of their entire sales and they have to make business decision on how bet to spend their limited resources. That's my point.
