Well, it is about time. BUT FAR TOO LATE IMHO.
MLB.TV is available on everything now, and includes LIVE TV game feeds, along with the radio version of every game for around $130 year($60 on Mother's day and $50 on Father's day he last 2 years).
Nice too hear they "FINALLY" got around to it, but other devices/services have arrived since they made the first deal, and those devices are VASTLY superior in everyway to SiriusXM.
Just wait until IP service is provided DIRECTLY into the car. Not too far off.
