Well most people have been waiting long for blue, and there hasn't been an update. Once after the blue info, there was hardly anything or nothing at all about blue. Once you wait for a long while, having no updates at all, people begin to lose faith, and suspect something. The team doesn't have to give screenshots or videos, they need to give info on the progress.
EX:
"The reason we have taken so long on an update was because we have rewritten blue. We have made a lot of progress and learned a few things while making the mod. Today we have synced drive bys, but we won't be sure if it is in the final release."
That is all there is to it. It hurts no one, because it is an update. Positive, or negative it does not matter. This shows more progress is being made into blue.
