Availability of the upcoming patch

So when the next patch for the game and Brave New World comes out(inevitably to fix balance issues and bugs present at launch) will it only be available to users for BNW, or will a patch also be released for vanilla/G&K if addressing other issues? For example, will a fix for the 'win as...' achievements that don't activate in G&K for users who didn't buy BNW? Also, will the rumored makeovers that Germany and Japan might get be available to G&K users or will it only be released for BNW?

I believe Firaxis said that the next patch will be the "Fall Patch" addressing issues in Vanilla and both expansions

I hope Firaxis does not take 6+ months to fix the problems with BNW (especially the problems with American and archeologist outside the territory).

This is not just a minor problem, but a issue that has been causing the game to crash, everytime.
