I just signed up today and even though it looked like it came with superfan since online it said "Up to 40 HD games a week" and then sign up for 59.99, it doesn't. A few minutes later all the games in SD were showing up but the -1 channels were not working. Called up directv customer service to either cancel the MLB EI or get the superfan.
So I basically did the same thing "Upnorth" did and the rep actually understood what I was saying as they saw that superfan was $50 in march just as it is now. First she tried to just have the system make me only pay one $25 payment. She couldn't get the system to do it though and just ended up giving it to me for free; we'll see on the next bill I guess.
Also, she said that if you signed up for EI this year it will auto-renew itself for next year; so if you don't want it make sure to call in to directv and tell them you don't want MLB EI early next year.
