The eMMC will die when it runs out of space. If a sector goes bad, it gets marked as bad and you loose the space. It is all handled by the controller inside the eMMC. Very similar to a Solid State Drive.
MTBF depends on how you are using it. Most likely thing to fail would be the processor so you can use the MTBF of that devices. BBB is development board, not an industrial solution. If you run this all full speed and high temperature, the MTBF will be shorter. I believe we are already at 5.0 on eMMC, assuming all features are activated via the kernel.
