Dota 6.68 Preview Video Got Delayed

Several days ago, IceFrog make a post on the PlayDota birthday that the Dota 6.68 is already "much more than half way through". However, today on his blog he also added that the Dota 6.68 video preview is got delayed because he wants to make sure the content is finalized first. Here is what IceFrog said:

With regards to the video trailer, I was originally planning to post it well in advance of the map release but I've decided to hold off on making it until more content is finalized. I'll post previews here when the map is mostly ready.

Well, honestly, i think the preview is much better if it is posted when the map still on progress and not when the map is ready to going out. But it's IceFrog decision anyway, let's wait for the map. And hey, Christiano Ronaldo still doesn't make a goal -_-
