GSP was out for what, 19 months? Not sure if it had a positive or negative effect. Could go either way. Condit just disappeared after his lackluster fight with Diaz which cost him fans. The prices are high, more PPV's.. the numbers are pefect imo. Silva-Sonnen II was obviously going to top the charts and Jones-Evans had a huge build to it.
Also it's important to note that college football is at the end of regular season right now here in the US and there some pretty big games going on like Oregon vs Stanford which was a big game for college football's national championship. I know I had 2 TV going so I could watch OU vs WV at the same time as the fights.
