Quinton Jackson vs. Matt Hamill upgraded to main event. Rick Story vs. Thiago Alves upgraded to PPV bout (from SpikeTV). Tim Boetsch vs. Kendall Grove upgraded from preliminary bouts to SpikeTV.
This card still has some interesting fights but I agree with oldmangrouch, without edgar/maynard 3 it has lost some "umph"
As far as I know hes never switched a card from PPV to being free, no? How would he even do that? Could/would Spike put it up on short notice? It'd be nice but its never happened even on other cards where the main event dissipates (i.e. when Lesnar/Carwin fell apart and Ortiz/Forrest 2 took its place).
do ppv's get ordered days before the day of the fights? i could see that as a reason for not switching, it would be a hassle to credit back the people that have already ordered the event.
I think they are pretty much locked in with the PPV provider to air it on pay-TV. Dunno if you get charged for a buy until it happens. I know if you buy something, don't watch/record it, you can get credit back on your account.
