Why would BMW state lifetime and not state say 130,000km to change the transmission fluid? It would be in their best interest to have you back at the dealership in 130,000km. So who, knows really.

I will change at 130,000km also.
You can do what you like my good man, but its a fact that no oil is lifetime oil whether its transmission, motor or differential oil. Besides the fact that after a certain number of kilometers switching gears feels like shit, your transmission will love you if you change the oil and shifts will be smoother than ever.

BMW is in the business of making money first and foremost. They are also the ones that claim their wastegates aren't lemons...
