I feel like it's been that way for a while now.
They have a deadline for mass-producing and marketing, and they shove them out the door, with the idea that the programmers etc. can keep on working during the time it takes for that process, and then release the patch.
Reminds me a bit of the way walkthough books are out-of-date because they had to print before final version to be profitable.
At any rate, Gothic3 is a game I'll have to check out. I'm not sure if I'll like it or not, but it seems worth trying, anyway.
