This is in line with F15 using the same engines as E70, benefiting instead from lighter weight and improved drivetrain. And it's been the norm for a very long time now for BMW to use the same engine with minor variations in many different models.
No idea what kind of transmission will be there - the source doesn't specify that.

For many that's the same engine, yeah, there are some variation, but basically it's the same.
People wants model specific dedicated M engines, but that is just unlikely to happen anymore.
