At GDC 2012 we got an interview with three writers from valve, that told us some pretty interesting information pertaining to our mysterious little friend. Pyro is the only class with out the "Meet the" video, and everyone has eagerly been awaiting for it. They have actually FINISHED Meet the Pyro, but they don't drop any hints as to what is really in it. In the interview with the three writers, they mention that it could be soon and that we most likely will be getting a big update that has to do with the release of the video. Most likely something similar to the Uber Update. We already knew it was bound to happen sometime this year, but at least we know they are one step closer to uploading the video.
About damn time.
