First Q3A DC will be released (in process now).   Once we've finished up Team Arena and finalized the 1.25 patch for Q3A, then we'll work on creating the DC map pack for PC users.  Exclusive DC content will not be included in the PC map pack (that's part of our deal with Sega).  What WILL be included in the PC map pack are the DC versions of the Q3A levels that are in the PC version.  This includes the DC textures, etc., so that PC players and DC players will be able to play one another. The PC map pack will probably come out some time after the first of next year.
