Aactually, adding more programmers does not improve update times. Any programmers brought on would take time to get up to speed on CCP’s code base. The work load then has to be divided amongst all, and vets spend less time programming and more time helping newer programmers understand the complexities of the code.
The end result is that until the new programmers are up to speed and comfortable, they are actually limiting productivity. This can take anywhere from a few months to a year depending on skill/ability of the programmer and complexity of the code.
Additionally, each change has to be tested. Unless resources are balanced properly (and I have yet to see any company where the resources are balanced well), more features means more testing but with limited resources increase the time to release.
Eventually this can all be balanced. However it may take up to a year or two.
Now here’s the other part… Valkyrie generated a lot of press for CCP. That is a good thing. What we don’t know is if the press and other benefits from Valkyrie exceeds, matches, or is less than what CCP would have gained had it focused on just EVE. Still to simply claim the time and money was better spent on eve is foolish as it is not So be easily quantifiable metric.
