Timetable for BMW 230i, M240i, M2 LCI updates and new engines

Summary of the upcoming 2 Series, M240i and M2 lineup:

2016 M2 – not LCI
2017 230i and M240i – not LCI, just new engines, plus whatever parts BMW adds across the board for the new model year (in this case wifi hotspot)
2018 230i and M240i – LCI with engines introduced a year earlier.
2018 M2 will get new LCI design features in the places that it shares with regular 2er cars. Whether it will also be called LCI, is unknown – BMW is very inconsistent in that regard when it comes to M cars.
