I would expect it stays at $55. It will take over three years of $55 payments for YouTube to make up the 30% cut that Apple takes in the first year. You don't need to sign up from an Apple device to use YouTube.tv on the device. Save your money and purchase the subscription directly from Google.
So i should just cancel before may 13th and sign back up through the website. Funny way to circumvent apple and keep all the profits.
