Early bird is $60. All games, live, on-demand, anytime, anywhere.
Sky Sport is 2 or 3 monthly billing periods (so at best $140), but you'd also have ad breaks (on a paid service for fudge sakes!), a 12-month minimum contract, no (or completely useless at best) on-demand offering with the rugby or any other of those sports. (Does the $70/month sky even include MySky/HD??)
I don't care much for Rugby, but if someone offered an all access pass to the Football World Cup for $60 I'd have bitten their hand off.
