Now I know this by no means breaking news but I checked through the CBM archives and I didn't see these videos posted anywhere. So this is just in case you die-hard Godzilla fans missed this one. I only found this about three or four months ago.
These are Toho co. movie grade short battle clips of Godzilla 2000 fighting Anguirus, Gigan 2004, and King Ghidorah. According to G-FAN, issue # 90, in an article entitled "Godzilla’s Back and Kawakita’s Got Him!", these short clips were made as a promotional piece for a video game being released in 2010
Obviously the intro wasn't filmed by ToHo, that's fan made and not horrible.
