I am really new at this speculating thing. But here is what I think. If the M2 is getting the B58, then it's very likely to not be an ordinary B58 (like N55 with some components from S55). I just don't think that BMW is going to do this since the M2 with N55 is receiving such a good review there is no need to invest in another bunch of money to make this change only after 1.5 years. My guess is that there will be a M2 with S55 as a special edition. Anyway I am expecting to take delivery of my M2 in 2 weeks and honestly I am having second thought. I want the new thing but having to wait around another 11 months (Sep 2017) is painful.. I guess eventually I will just get the car and enjoy it for now
