The thing about this is that the Xbox version is far more complicated to update than the PC version. Frontier has direct control over the PC version updates, whereas updates have to go through Microsoft Update software first for Xbox. It means that future updates after Xbox release and CQC will likely come to PC first before Xbox, simply due to the ease of updating on PC. The counter to that is that we have to deal with the bugs and issues first, whereas Xbox will likely get the cleaned up copy after we sort out the problems (Because lets face it, even with betas, there are still problems upon release - See powerplay).
You can go back over old information about which ships were already verified to be added to the game in later content. And in the E3 conference, Barben stated that there are plans for other ships besides those as well, that were not mentioned previously. Get your credits now Commanders, build up your bank!
