I didn't think there was a chance in hell that bumper would be from the M2.
But now this picture leaked of the 3-series LCI headlights and in the back you can see what look like 2-series headlights but with gloss black extensions which could make them fit into that M2 bumper.
Edit: Actually on second thoughts...putting the 2 pics next to each other. I don't think they would fit honestly
