Cheap, a la carte games make lots of sense from a consumers point of view...from the providers point of view, I am not so sure, as I would think it would actually cut into their revenue, not increase it...
For example, if you're a fan of an NFL team, and live out of market, and want to see every game your team plays, you pretty have to pony up for the full price of NFL Ticket...at what, $200? Sure, you actually then get ALL the NFL games, but if you only care about your team, most of those games go to waste, even though you're still paying for them...
If they went with a la carte model, how many people do you think would drop the full package option, and only pay the few bucks to watch the handful of games that actually interest them? My guess, quite a few...
Hopefully, a la carte pricing model...not just of sports, but for channels and TV shows will become the norm... we're still a long way away from that I am afraid...
