Read the Soren Johnson Chat Transcript some things have been revealed about the patch in that... Also Jef Morris posted some information on it.
This comes right out of the chat transcript:
[ACS_MarkG] let's get the upgrades/patches question out of the way no
[Soren_Johnson_Firaxis] cultural acquisition of cities does not make the AI get mad b/c
[ACS_MarkG] Soren, what decisions are there right now for the patches?
[Soren_Johnson_Firaxis] it is not really directly under the user's control (unlike capturing a city) * nidz-onehalf would like to ask a rather silly, but fun-to-know question
[Jannekorv] ok, thats the only way I aquire cities so
[connorkimbro] Soren_Johnson_Firaxis: i've noticed that alot of times, the AI seems to really like to share techs with other AI civs. . but not with the player. It's almost as if, diplomatically, they're ganging up on the player. Is that intentional?
[Soren_Johnson_Firaxis] oh sorry... we are working on a patch and it will address bugs and interface issues first as well as a few balance and AI holes...
[ACS_MarkG] upgrade on the editor?
[Mark13] Any hint of a release date?
[Soren_Johnson_Firaxis] ...sorry, I can't be too specific b/c we don't want to promise anything until it gets through testing...
[ACS_MarkG] Ok, thanks
[Misfire] ?
[Soren_Johnson_Firaxis] the editory will be upgraded soon although I am not sure if it will be in the first patch...
[SamSmithnz] But we're talking before christmas for the patch right?
[ACS_MarkG] thechief, please ask
[TheChief] Is simple trespassing enough of an excuse to start a war with an AI player without losing points with other AI players. In other words, I don't want to ruin my reputation in the long run to win by the UN vote.
[Soren_Johnson_Firaxis] yes, before X-mas
[ACS_MarkG] yes, sam, Jeff Morris mentioned "end of month"(this month).
Hope this helps...
